Вид ресайклера, показывающий повторяющиеся элементы

Question

У меня проблема с представлением моего ресайклера, он показывает все элементы два раза. У Activity есть два вида ресайклера, оба с разными адаптерами, но оба являются дублирующими элементами. Но когда я обновляю sh свое представление ресайклера с помощью onRefreshListener, оно отображается правильно.

Я использую тот же метод, который используется в onRefreshListener, но когда мой фрагмент запускается и вызывает тот же метод, он показывает повторяющиеся элементы, но когда я использую тот же метод в onRefreshListener, он отображается правильно
