Description of issue:
I’m trying to download “The Eminence in Shadow” (Japanese “Kage no Jitsuryokusha ni Naritakute!”) from a specific release group called “Anime Chap”. I have a release profile that has “Must Contain” set to “[Anime Chap]” and “Anime Chap” using Nyaa.si as an indexer via Prowlarr. This has worked without issues. The actual error I’m getting is that sonarr fetched and downloaded the first 9 episodes without any issue and marked the other ones (10 to 13) as “unknown series”. I have confirmed this via manual search where the episode from “Anime Chap” is found, but is marked that way. The naming format that the release group uses is constant, so I see no reason as to why this has happened. Any help would be greatly appreciated.

Likely because the parser can identify/handle S01E0# format but not S01E1# for some reason. So it can parse out the series name properly for eps 1-9, but after that it thinks the episode number is part of the series name and obviously fails to identify it at that point.

Might be fixed in v4, otherwise you might need to request a sonarr scene mapping since the series is continuing. Link Will be very important to fill in the form completely and provide accurate release name since it appears to be a parsing issue.
