android recyclerview – ViewPager Fragment RecycleView Reset

I have 3 fragments in the viewpager
Personal Fragment (1), CropFragment (2), NotesFragment (3)
Each fragment contains recyvleview and I added elements to it for each dialog, but each time I passed to the last fragment (NoteFragment), the first (PersonalFragment) recycleview fragment was null (removed all items) and was identical to the one that was returned to the first fragment, the last fragment was recycleview. reset (delete all items).
