When updating to iOS14 I lost all connections to my iPad files

I keep all my music in the local djay folder on my ipad. I then access that through the files folder (at the bottom of the music sources list), and from there build all my sets and playlists.

When I upgraded to iOS14 all these folders became greyed-out. I can reload new versions of these folders, BUT, even though I still have my cue points for those songs, the songs in my playlists say “The track cannot be played because it is not available.”

Why did this happen? Do I need to recreate all my sets again?

Thank you,
Chony
