Description of issue: Sonarr fails to pick two out of ten anime shows. It is configured to download the ASW releases from Nyaa through Jackett (a lot of moving parts).
In the first case (Tsuki to Laika to Nosferatu), the correct torrent is pulled from Jackett, however for some reason Sonarr fails to recognise it as a valid series.
In the second case (Yakunara Mug Cup mo) Sonarr fails to find the correct torrent, however it can be found with manual search in Jackett.
