Recyclerview in Nestedscrollview hides last item when getting back from fragment

Question

I just need some hint on this. I have fragment A & Fragment B.

Fragment A --> Fragment B

At first launch, the layout is of Fragment A is fine (Picture 1: first screen initial /2. first screen when scrolled). But after going to Fragment B, & returning back to fragment A. The last item in recyclerview goes below screen by about 60 dp as shown in Picture 3. I added marginBottom (60dp) at NestedScrollView and could see the last item at returning back. But it gave margin at first launch of fragment.

I think there is problem of CoOrdinatorLayout and NestedScrollView but couldn't solve this problem.

Layout of Fragment A :

Add on class file

mRecyclerview.setNestedScrollingEnabled(true);
