Others can't view my playlist

[drewfyyy]

Me and a friend were sharing playlists, but when she found mine, it was simply the name of the first song in the playlist, and that song. I've set it to private then back to public, made it collaborative, signed out and signed back in, and even removed that song from the playlist, but it still shows that it is the only song in the playlist. Also, this is the only playlist of mine that does this. Please halllppp
