Android Navigation Bottom Fragments Overlapping

I am using a navigation bottom with 4 items in my app, so I have 4 fragments. the first fragment(home page) contains a recyclerView and other fragments don't contain any recyclerVi

Solution 1:

I have used navGraph in my fragment in the XML file previously and I've forgotten to delete the navGraph, so it was showing the first fragment in the navGraph in the background.
