Anime episode past 100 parsing wrong episode

Sonarr version (exact version): 2.0.0.5344
Mono version (if Sonarr is not running on Windows): 5.20.1.34
OS: Debian Buster
Debug logs: https://hastebin.com/yiwapacusi.md
Description of issue:
Sonarr is parsing an anime episode of 125 => s1e25 when it should be s1e125. See here (also in pastebin):

[Debug] Parser: Parsing string 'Black Clover - 125 (1080p FUNI WEB-DL -KS-)' 

[Trace] Parser: ^(?<title>.+?)?(?:(?:[-_\W](?<![()\[!]))+(?<season>(?<!\d+)[1-9])(?<episode>[1-9][0-9]|[0][1-9])(?![a-z]|\d+))+ 

[Debug] Parser: Episode Parsed. Black Clover - S01E25  

Here’s an episode that parses correctly, even though they’re the same naming scheme.

[Debug] Parser: Parsing string '[Golumpa] Black Clover - 119 [FuniDub 720p x264 AAC] [34621C92].mkv' 


[Trace] Parser: ^\[(?<subgroup>.+?)\][-_. ]?(?<title>.+?)(?:[. ]-[. ](?<absoluteepisode>\d{2,3}(\.\d{1,2})?(?!\d+|[-])))+(?:[-_. ]+(?<special>special|ova|ovd))?.*?(?<hash>\[\w{8}\])?(?:$|\.mkv) 


[Debug] Parser: Episode Parsed. Black Clover - 119  

Thoughts?

If I’m not mistaken: you have [something] in front of the second episode, triggering sonarr to use its anime regex, rather than standard episode regex for the first one.

[markus101]

Yeah, this is the reason. 125 is pretty ambiguous to Sonarr, before anime it was always S01E25, with anime it depends on whether there is a release group anchoring it. v3 makes some improvements, but it’s not going to be flawless.

Thanks for the quick reply and info @markus101 and @Thirrian. Is there any way I can customize the regex triggers? If not is there a commonly used workaround that others may use to fix the mislabeled episodes? Here’s the mislabeled episode inside the series:

So when sonarr stores this it also renames it wrong (s01e25) which is causing issues in plex. It’s also a non-tracked episode so thankfully it’s not overwriting anything.

[markus101]

You can’t customize the regex, you’ll want to either add a release group to the file or move it out of the series folder to another location on disk, then use Manual Import on Wanted: Missing to import it, then you can override the episode that Sonarr defaults to before importing.

@markus101 thank you for always helping the sonarr community!
