Deleted shows still visible on Emby

[xooni 1]

Hi all, I host emby on a synology, running radarr and sonarr. When I delete a movie on radarr, emby syncs appropriately and removes the movie. However, I have a problem with deleting shows from sonarr. The episode files will delete successfully and be removed from emby. But the show poster and landing page are still on emby. I have to delete them manually. Is there something I'm doing wrong? Thanks.

Are there left over files / directory left over in your file system ?
