Add Playlist Songs (to library) GLITCH

So my issue is:

There is this option that I have ALWAYS had off. Called, “add playlist songs”. It adds any songs that you put on a playlist, to your main library screen as well. I have always had this off as I do not want this. For some reason, when I add a 1 song to a playlist, it works like it’s supposed to and JUST adds it to the playlist. But for some reason after I add that 1 song, it AUTOMATICALLY turns that “Add Playlist Songs” setting back on. So, if I add another song it adds it to the main library screen. I toggle that option back off, tried adding this song to the playlist again, and it just automatically turns the option back on and add it to the entire library again. I’ve tried different songs. It does the same thing, despite me, turning the option off every time.

I reset my phone that did not help.

And I am on an iPhone 14 Pro Max

The bug only occurs on my phone, not my MacBook. However, if I add a song via my MacBook, it still turns the option on on my phone.
