No Longer Able To Move Books To 'add To Collection'.

I used to be able to save my books/games to the Add Book to Collection w/o any problem. I would save a book read/game to a category called Books Read or Games. By doing so, the book/game was no longer displayed in the Home view. Now when books are saved to these categories, they are stored there, but still appear in the home screen. The purpose of saving is to eliminate a cluttered Home screen. This is no longer possible. Any help will be appreciated.
