Sonarr version (exact version): 2.0.0.5344 Mono version: 5.20.1.34: OS: Ubuntu 18.04.4 LTS (https://docs.linuxserver.io/images/docker-sonarr) Debug logs: (non applicable I think) Description of issue: When using the rename functionality (from UI) most of the times it cannot find the release group on a previously renamed file, check in the screenshot that “Judas” is lost from the original to the renamed one
Looks like the original format follows an odd crossover between standard formats (season + episode numbers) and release group in square brackets, so Sonarr likely never parsed the release group (and lost track of the file so it doesn’t have that information stored).
In this case “standard” refers to season + episode number, the “Standard” Series Type in Sonarr.
-ReleaseGroup at the end if you’re using season + episode numbers [RlsGrp] if you’re using absolute episode numbers, if you’re using both, then -ReleaseGroup might be your better option.
