Movies don't show image when restoring backup

This application is my favorite but there is a problem with it that I noticed with time of use.

When I restore the backup, the image of the series uploads when synchronizing, but the movies do not and I have to click one by one for the image to be loaded and it is a very tiring process.

Is there a trick to fix this? My language is not English, which according to the F.A.Q mentions the images are only loaded when configured for this language option, but the problem still persists with the movies.

Would it be possible for a future update to include the images of the films and series in the backup so that there is no problem even after synchronizing with the internet?

Thank you very much.
