You can force Collections to sort at the top by renaming them. I stumbled on using an apostrophe before the name of the Collection, and that pushes them to the top. For example, I have Collections named as follows:

'Loans
'Classic Crime
'Science Fiction

Still, all of your books will follow the Collections, and the best you can do is ignore them.

Alternatively, you can leave your Collections named as they already are and, in your library view, go to the Filter icon on the left side of your screen (3 horizontal lines with circles on them) and select Collections (you should also have List selected here). If you do this, you will have to go to your Home Page to add new books to your collections.
