Media artwork all mixed up following sync

I'm just wondering if anyone can help?...

I've recently upgraded to the iPhone 18 pro. I've transferred everything over and it all appears to be fine, but I'm having one major issue with the media - All artwork seems to be wildly mixed up for music, tv shows and films.

It was all fine on my previous iPhone and this happened prior to updating to Golden Gate.

All artwork appears to be present and correct on my macbook, within iTunes and TV, but when it's moved over to the phone, it's all over the place - I've added some pictures for clarity...

I've searched for solutions and have tried the following:

• Taking all media off and re-syncing (both via cable and over wi-fi)
• Deleting ~/Library/Containers/com.apple.APMArtworkAgent/Data/Documents (on macbook), shutting down and restarting both macbook and iPhone, then syncing
• Swearing at both my macbook and iPhone

Nothing seems to work.

Anyone have any ideas?
