Элементы Recycler исчезают после перехода на другие фрагменты

Question

public class Employee_mainScreen extends AppCompatActivity {
private ViewPager viewPager;
Button logout;
FirebaseAuth mFirebaseauth;
private FirebaseAuth.AuthStateListener mAuthStateListener;
e_HomeFragment homeF;
e_ProfileFragment profileF;
e_MessagesFragment messageF;
e_SavedFragment savedF;

private BottomNavigationView.OnNavigationItemSelectedListener e_navListener =
        new BottomNavigationView.OnNavigationItemSelectedListener() {

            @Override
            public boolean onNavigationItemSelected(@NonNull MenuItem item) {
                Fragment selectedFragment = null;

                switch (item.getItemId()) {
                    case R.id.nav_home:
                        selectedFragment = new e_HomeFragment();
                        break;
                    case R.id.nav_saved:
                        selectedFragment = new e_SavedFragment();
                        break;
                    case R.id.nav_messages:
                        selectedFragment = new e_MessagesFragment();
                        break;
                    case R.id.nav_profile:
                        selectedFragment = new e_ProfileFragment();
                        break;
                }

                getSupportFragmentManager().beginTransaction().replace(R.id.e_fragment_container,
                        selectedFragment).commit();
                return true;
            }
        };

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.e_employee_mainscreen);

    BottomNavigationView bottomNav = findViewById(R.id.e_bottom_navigation);
    bottomNav.setOnNavigationItemSelectedListener(e_navListener);

    getSupportFragmentManager().beginTransaction().replace(R.id.e_fragment_container,
            new e_HomeFragment()).commit();}}

Это мои коды для экрана, где моя нижняя навигация равна

public class e_SectionsPageAdapter extends FragmentPagerAdapter {

private final List<Fragment> mFragmentList = new ArrayList<>();
private final List<String> mFragmentTitleList = new ArrayList<>();


public void addFragment(Fragment fragment, String title){
    mFragmentList.add(fragment);
    mFragmentTitleList.add(title);

}

public e_SectionsPageAdapter(FragmentManager fm) {
    super(fm);
}

@Nullable
@Override
public CharSequence getPageTitle(int position) {
    return mFragmentTitleList.get(position);
}

@Override
public Fragment getItem(int position) {
    return mFragmentList.get(position);
}

@Override
public int getCount() {
    return mFragmentList.size();
}
}

Это адаптер моей нижней навигации

public class e_HomeFragment extends Fragment {

private RecyclerView mrecyclerView;
private JobsAdapter adapter;
FirebaseAuth mfirebaseauth;
private DatabaseReference mdatabase;


@Nullable
@Override
public View onCreateView(@NonNull LayoutInflater inflater, @Nullable final ViewGroup container, @Nullable Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.e_fragment_home,container,false);
    mfirebaseauth = FirebaseAuth.getInstance();
    mrecyclerView = view.findViewById(R.id.recycler_View);
    mrecyclerView.setHasFixedSize(true);
    mrecyclerView.setLayoutManager(new LinearLayoutManager(getActivity()));
    String user_id = mfirebaseauth.getCurrentUser().getUid();
    FirebaseRecyclerOptions<Jobs> options =
            new FirebaseRecyclerOptions.Builder<Jobs>()
                    .setQuery(FirebaseDatabase.getInstance().getReference().child("Jobs"), Jobs.class)
                    .build();

    adapter = new JobsAdapter(options);
    mrecyclerView.setAdapter(adapter);

    return view;
}

@Override
public void onStart() {
    super.onStart();
    adapter.startListening();
}

@Override
public void onStop() {
    super.onStop();
    adapter.stopListening();
}
}

Это мой домашний фрагмент, гдепредставление переработчика пожарной базы

public class JobsAdapter extends FirebaseRecyclerAdapter<Jobs, JobsAdapter.JobsViewHolder> {

private DatabaseReference UserRef;

public JobsAdapter(@NonNull FirebaseRecyclerOptions<Jobs> options) {
    super(options);
}

@Override
protected void onBindViewHolder(@NonNull final JobsViewHolder holder, int i, @NonNull Jobs jobs) {

    String userID = getRef(i).getKey();
    UserRef.child(userID).addValueEventListener(new ValueEventListener() {
        @Override
        public void onDataChange(DataSnapshot dataSnapshot) {
            String c = dataSnapshot.child("company").getValue().toString();
            String d = dataSnapshot.child("description").getValue().toString();
            String p = dataSnapshot.child("position").getValue().toString();

            holder.Pos.setText(p);
            holder.Des.setText(d);
            holder.Com.setText(c);

        }

        @Override
        public void onCancelled(DatabaseError databaseError) {

        }
    });


}

@NonNull
@Override
public JobsViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
    View view = LayoutInflater.from(parent.getContext())
            .inflate(R.layout.e_layout_listitem, parent, false);

    UserRef = FirebaseDatabase.getInstance().getReference().child("Jobs");

    return new JobsViewHolder(view);
}

public class JobsViewHolder extends RecyclerView.ViewHolder{

    TextView Pos, Des, Com;

    public JobsViewHolder(@NonNull View itemView) {
        super(itemView);

        Pos = itemView.findViewById(R.id.titleTv);
        Des = itemView.findViewById(R.id.companyTv);
        Com = itemView.findViewById(R.id.descriptionTv);


    }
}
}

А это адаптер переработчика пожарной базы

Спасибо за все ответы, которые я получу

Мне действительно нужно это исправить в ближайшее время
