I need help removing custom lyrics on Iphone BUG

Hi yesterday I added some custom lyrics to a song on Mac, but now i want the auto-generated ones. so

I know how to put in custom lyrics, and I know how to remove them, and On Mac it works. The problem is that I'm trying to remove the custom lyrics on Iphone and it's not removing them. On Mac It asks me if I want to remove it and tells me that they won't be viewable once I check the box, but every time I go back to the song on Iphone (saved in the library or playlist) the custom lyrics are there. It acts like I didn't check the box or clicked yes to remove them. I've tried to restart my device, force closing Music, disabling and re-able library synchronization on Mac and Iphone.

My current version of IOS is on 14.6 and MacOs is on 11.4 (Big Sur)
