Navigation bar is buggy

As the title suggests, the navigation bar has some problems; 2, to be more exact:

1) the option to change its layout doesn't work (it only shows the “home” and the artist stats options and the rest of the page is all gray)

2) I cannot make the home section the main one when I open the app. If I select it, the app instead opens on the new “reels” feature or whatever. If I select any other option, it works
