Why does my tablayout always do the current tab selected and the next tab?

I have an activity that uses a tablayout with 3 tabs. When the activity is started, it initializes (onAttach, OnCreate, OnCreatView) for tabs 1 and 2. When I select tab 2, it initializes tab 3. Does tablayout automatically do this for a reason or is there a way to tell it not to get ahead of itself.

The following is the activity java code

        MobileAds.initialize(this, new OnInitializationCompleteListener() {

        });

        mAdView = findViewById(R.id.adViewCheckInNewCurrentLocation);
        AdRequest adRequest = new AdRequest.Builder().addTestDevice(AdRequest.DEVICE_ID_EMULATOR).build();
        mAdView.loadAd(adRequest);

        final ViewPager viewPager = findViewById(R.id.check_in_new_main_pager);
        final PagerAdapter adapter = new CheckInNewMainPagerAdapter
                (getSupportFragmentManager(),

    }

    @Override
    public void onFragmentInteraction(Uri uri) {
    }

    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        Log.i(TAG, "CheckInNew onCreateOptionsMenu: ");
        getMenuInflater().inflate(R.menu.check_in_new, menu);
        return true;
    }

}

The following is the pager adapter for the tabs.

package com.grgapps.checkingin;
import android.util.Log;

import androidx.fragment.app.FragmentPagerAdapter;
import androidx.fragment.app.Fragment;
import androidx.fragment.app.FragmentManager;
import static androidx.constraintlayout.widget.Constraints.TAG;

public class CheckInMainPagerAdapter extends FragmentPagerAdapter {

    int tabCount;

    public CheckInMainPagerAdapter(FragmentManager fm, int numberOfTabs) {
        super(fm);
        Log.i(TAG, "CheckInMainPagerAdapter: ");
        this.tabCount = numberOfTabs;
    }
    @Override
    public Fragment getItem(int position) {
        switch (position) {
            case 0:
                Log.i(TAG, "CheckInMainPagerAdapter Case 0 getItem: ");
                return new CheckInRecentList();
            case 1:
                Log.i(TAG, "CheckInMainPagerAdapter Case 1 getItem: ");
                return new CheckInApproveRequested();
            case 2:
                Log.i(TAG, "CheckInMainPagerAdapter Case 2 getItem: ");
                return new CheckInSearch();
            default:
                return null;
        }
    }
    @Override
    public int getCount() {
        return tabCount;
    }
}

It is because of your ViewPager offscreen page limit. By default, it is 1. It means the right and left fragments are loaded. Please refer to the documentation for more information
