Description of issue: Sonarr is not detecting episodes from specific Season. In this series, it is detecting the files for Season 1&6 but not 2-5. My first thought was permissions but the permissions are identical between the Seasons for both the folder and the specific video files within those episodes. Has anyone seen anything like this?
