There are so many threads in this forum that deal with the display of covers in players where it apparently is the wrong one.
I found these with the search words "player wrong cover"
Could you search for some more if they don't help?
And hoenstly: it is a player problem as the only program that shows what you expect is MP3tag. And Mp3tag will help you to get the data right.
E.g. you could filter for files that have a cover with
%_covers% PRESENT
and then see if any files pop up where you did not expect a cover.
Also, it may help if you showed us the extended tags dialogue of a single file that is displayed with the incorrect cover.
