Your description says you are using set lists for each book - you should be using collections (A collection only allows one copy of a song). The alphabet appears when a collections is sorted alphabetically.

You can easily convert a set list to a collection - Long press the setlist name until an arrow appears against it. Then tap the three vertical dots at top right corner and select "Create Collection from Songs".

If you really need an "All Songs" collection, long press one of the setlists (or collections) and tap the remaining set lists (collections). Perform a Create Collection operation
