Problem with reloading Fragments in Navigation component

Question

I have navigation with multiple backstack. Everything is done as in https://link.medium.com/z34TYZxorpb except that the fragments go in a circle

the problem is that when I go through this and go back to the previous fragment, the fragment does not save data and the view is reloaded

Edit:

I noticed one thing that when I use the coordinator layout in xml, then at this moment it is not saved after returning to the backstack
