apple iphone books app displaying wrong cover art

[sovre]

I recently got an iphone 11 which is running ios 14.

I have some audiobooks which I want to add to my phone to listen to them.

They all display correct coverart in iTunes.

However, when I transfer them to the Books app on my phone, they show up there with the wrong coverart.

not only that, it looks like for whatever reason my phone is taking coverart from music albums on my phone and using that in place of the proper audiobook covertart.

I assume this must be a result of some kind of major bug in apple's software. My old phone, an iphone 7+ running ios 13, always displayed correct covertart without a problem.

unfortunately, and frustratingly, apple doesn't allow you to change coverart on the phone itself, and if I simply transfer the book again from itunes it doesn't correct the problem.

Has anyone else experienced this and if so, is there a way to get the right coverart to display?

Thanks.

I would ask about this in the support forums at apple.com. I doubt there are many people happening by here that would have experience with this.
