duplicated songs on iphone

All of my songs in albums on my iphone music seem to be duplicated but they are not duplicated on my Itunes on my pc. My phone is Iphone 2020 SE and is up to date on IOS 16.7.2 I have over 1800 songs on my itunes and have tried syncing several times. I have checked my apple ID is the same on the PC and the phone and I have tried manually deleting some of the duplicate tracks on my iphone music but as soon as I sync the phone they become duplicated again ???

Any suggestions on how to sort this would be appreciated.
