Результаты не отображаются в поле зрения

Question

Недавно я обнаружил, что результаты экзаменов учащихся больше не отображаются в определенном классе (ПРЕДШЕСТВЕННИК).

Возвращаясь к форме, где добавляются результаты, я вижу, что результаты были повторно заселены и уже хранятся в базе данных.

Однако они не отображаются в представлении. Интересно, что должно быть не так.

модель

 public function getRecentmtGradesRN($id) 
    {
            $this->db->select('*');

            $this->db->where('student_id', $id);

            return $this->db->get('mtscores_rn')->result();

    }
