Child’s phone being stuck using my Apple Music and not her own access with her own Apple ID

I purchased My daughters iPhones and set them up on family sharing to give them access to Apple Music. One set up well, she has access to music and can make her own play lists. The other however seems to have access to my main account as can change my playlist, play counts etc. I’ve spent hours going in circles thing to fix this but most advice says logout on her device but I can’t as she is under 13.

When comparing the girls phones they are both logged in under their own different Apple ID’s.

Any advice on how I can get her onto her own account and stop accidentally messing with mine would be greatly appreciated.
