Let’s work this thing together.
I did a complete restore of my last backup from the main ipad
The song lists came in there when you pick a name there no songs showing
I went to a list name and went to Add Songs
I selected all the song names that are showing in Local
The titles arrived and the songs play but there are no lyrics in any of them
This hasn’t happened to me before either! The two things that are different are the existence of Local songs, and using the iPad as a slave.
