Error 90032 when submitting to AppStore

I’ve got a finished game, that I want to submit to the App Store, but Application Loader gives me “error 90032”, and lists some icons that are not present in the game’s IPA.
I’ve configured and set all of the needed icons in unreal, so I guess, this is something that is new in the App Submission process, but ue4 didn’t yet keep up with it.

Is there a workaround for this?

(I’ve tried with Engine version 16,17,18, and got the same results)
