If you only want to see Collections, then set Filter to Collections; you can sort by Recent or by Title. Otherwise, they’ll be ‘mixed in’ with books. You can also sort by Collection, and they’ll be at the top of the list in Title order, followed by books in Recent order. It’s possible that the latter used to have collections in Recent order, but I never have it set that way so I would not have noticed such a change.

You don’t need to go to Home. Just stay in Library and open books from there. When you close the book, you’ll be back in Library, not Home.

I don’t use Airplane mode ever, but assume whatever it is showing there was downloaded at some point in the past when Airplane mode was not on and it connected.
