Add Playlist Songs to Library setting will not remain off

Whenever I try to add a song to one of my playlists, it adds the song to my library. I have tried multiple times to shut off “Add Playlist Songs” in music settings, but every time I add a song to a playlist after doing so, it turns back on for no discernible reason. I have updated my phone to the latest software and shut down my iPhone in an attempt to fix the issue, but to no avail. This has been happening for about two days at this point and is extremely frustrating.
