Apple Music Collaborative feature Deleting songs

I use apple music on android and recently marked my Playlist I've been curating for a couple years now as collaborative to try out the feature. Once marked, my Playlist now only has 100 songs on my original account, and the collaborative Playlist only has about 60 songs. I have NO IDEA what my songs were or how to get them back onto the Playlist. Unfortunately, I didn't notice until I had already marked several Playlists as collaborative, so this exact thing has happened with several playlists. Anyone else having this issue or know how to fix?
