更改后，RecyclerView不会保持修改状态

As you may notice my app has a navigation drawer, when trying to fix the problem by overridig the onBackPressed() in fragment, I tried to get back to the first fragment in my navigation drawer, when doing so I realize an error that I had not realized before:

NavigationUI.onNavDestinationSelected(menuItem,navController);

This line was duplicated in the NavigationItemSelectedListener:

        navigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
            @Override
            public boolean onNavigationItemSelected(@NonNull final MenuItem menuItem) {
                int id=menuItem.getItemId();
                //this line indicates the action of changing fragment using navController reference
                NavigationUI.onNavDestinationSelected(menuItem,navController);
                if (id==R.id.nav_cuanto){
                    Handler mHandler = new Handler();
                    mHandler.postDelayed(new Runnable() {
                        @Override
                        public void run() {drawer.closeDrawer(GravityCompat.START);}
                    },300);
                }
                if(id==R.id.nav_reportes){
//                    NavigationUI.onNavDestinationSelected(menuItem,navController);  -> this line caused the hole problem
                    Handler mHandler = new Handler();
                    mHandler.postDelayed(new Runnable() {
                        @Override
                        public void run() {drawer.closeDrawer(GravityCompat.START);}
                    },300);
                }
                if(id==R.id.nav_about){
                    Handler mHandler = new Handler();
                    mHandler.postDelayed(new Runnable() {
                        @Override
                        public void run() {
                            drawer.closeDrawer(GravityCompat.START);
                        }
                    },300);
                }
                return true;
            }
        });

I deleted the line and everything worked just fine, as expected, this particular method creates a new instance of the fragment you are trying to navigate to, but the problem is that when you try to navigate to the fragment you already are in, it creates a new instance a navigate to it, and this new instance is on the over the old one, so when back pressed the app do not return to previous view, but to the same fragment with the old view (out of date, of couse), I couldn't imagine this behavior, this is highly not imaginable, and it's not in the docs so I almost die trying to understand. So WARNING: if someone is trying to use

NavigationUI.onNavDestinationSelected(menuItem,navController);

请勿在同一通话中多次使用它，如果是这样，在最佳情况下，您需要按两次：-(
