Multiplying Favorite Folders

Since the past couple of upgrades to my iPad (gen. 4), When I go to the Main Library, the Favorites folder has multiplied, and there are now nine of them! (And all of them are empty). Is there a way to delete these and go back to just one?

Yes, to delete a custom collection, press the Edit button (top right corner), then tap on the collections you want to remove. You will see a checkmark indicating each item you select. Then, press Remove (lower left corner). Any custom collections you've selected (like Favorites) will be removed.

(As a side note for reference: If you select any standard built-in collections and choose Remove, they won't be removed in the same way as a custom collection. Instead, what it does is uninstall [undownload] all the books/items in the collection.)

Yes, thank you. I figured this out this morning. But then, this evening, two more popped back up. When I first open the app, it pauses with a horizontal line through the middle of the screen and says "Gospel Library Updating" and then when I go to the Library, I have an extra favorites folder. A new one appears every time the app updates.

That's an interesting bug! You could try deleting and reinstalling Gospel Library to see if that fixes the problem (make sure you're signed in to your LDS Account so all your annotations get backed up before deleting the app).
