MacOS metadata not displaying movie poster

On Apple TV my movie posters display correctly but on MacOS about 10% of posters don’t display. When I right click, it has the correct movie information and the thumbnail for the poster shows but when I select it, the poster still doesn’t display. When I select the film, it displays the background image and movie information.

Any ideas?

Could you provide a screen cap of what you’re seeing? Also maybe provide a movie name you’re seeing the blank poster with?
