No, it's a language issue. When Emby is set to Dutch, it's querying for Dutch season posters. Unfortunately these are not so readily available compared to the English versions, so Emby will create its own when it cannot find a poster. Now you can go through all series manually and use the all language option to search for posters, though this doesn't always seem to work. You can also remove all local meta data (the nfo's), or set the preferred language to English and then search in English. Resu
