[BUG] NavigationAdvancedSample - Change default item of bottom navigation

[RezaKardoost]

I added second line to change default item of bottom navigation (Leaderboard).

if (savedInstanceState == null) {
            findViewById<BottomNavigationView>(R.id.bottom_nav).selectedItemId = R.id.list //added this line
            setupBottomNavigationBar()
}

it works but there is a bug when selecting bottom navigation items. for example when I select this items respectively [Home -> Register -> Home]:
