fragment's onCreateView called multiple times

So I have a Settings fragment whose onCreateView gets called multiple times. I have ViewPager which is inside of the fragment's layout and the fragment launches by a clicking on the settings icon from options menu in toolbar.

And I cannot just move the ViewPager to the activity because I want to be able to swipe back to the Previous Fragment.

Also,I tried removing the fragments in the backstack using

for(int i=0;i< Objects.requireNonNull(fm).getBackStackEntryCount();++i){
      fm.popBackStackImmediate();
   }

but that did not help at all.

Fragment code:

public class SettingsFragment extends Fragment {
    
    public SettingsFragment() {
   
    }


    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

    }
    @Deprecated
    @Override
    public View onCreateView(LayoutInflater inflater, final ViewGroup container,
                             Bundle savedInstanceState) {
        final View rootview = inflater.inflate(R.layout.fragment_settings, container, false);
        final CustomViewPager viewPager=rootview.findViewById(R.id.SettingsFragmentViewPager);
        viewPager.setAdapter(new Adapter(getFragmentManager()));
        viewPager.setOffscreenPageLimit(2);
        viewPager.setCurrentItem(1);
        viewPager.addOnPageChangeListener(new ViewPager.SimpleOnPageChangeListener() {

            @Override
            public void onPageSelected(int position) {
                if (position == 0) {
                    viewPager.setPagingEnabled(false);
                    FragmentManager fm=getFragmentManager();
                    for(int i=0;i< Objects.requireNonNull(fm).getBackStackEntryCount();++i){
                        fm.popBackStackImmediate();
                    }
                    viewPager.removeOnPageChangeListener(this);
                }
            }


        });
        return rootview;
       
    }

The adapter I am using for ViewPager:

public class Adapter extends FragmentStatePagerAdapter {

    public Adapter(FragmentManager fragmentManager){
        super(fragmentManager,BEHAVIOR_RESUME_ONLY_CURRENT_FRAGMENT);

    }


    @NotNull
    @Override
    public Fragment getItem(int position) {
        if(position==0){
            return new BlankFragment();
        }

        if(position==1){
            return new SettingsFragment();
        }


        return null;
        }




    @Override
    public int getCount() {
        return 2;
    }


}

I see that in my adapter I am also returning SettingsFragment.Is there a way to return the fragment that was created when I clicked the settings button in the toolbar?

Btw, I add the fragment using this:

    @Override
    public boolean onOptionsItemSelected(MenuItem item){
        switch(item.getItemId()){
            case R.id.updateId:
                Log.d("MAIN ACTIVITY---","ADDING FRAGMENT...");
                FragmentTransaction ft=getSupportFragmentManager().beginTransaction();
                ft.setCustomAnimations(R.anim.push_right_in,0);
                ft.add(R.id.MainActivityConstraint,new SettingsFragment());
                ft.commit();
                Log.d("ACTIVITY---","Fragment added...");
                break;

               }
}

I decided to use an external library called swipebacklayout instead of ViewPager.
