Sonarr is unable to determine the series a release is for

Sonarr version:
Mono version:
OS: Ubuntu 20.4 (docker)
Description of issue:

HI, Sonarr doesn’t seem to be able to get episodes of the 2nd season of quintessential quintuplets. When I search them manually I get this message next to episodes matching my tags: “Sonarr was unable to determine which series and episode this release was for. Sonarr may be unable to automatically import this release. Do you want to grab ‘[Golumpa] The Quintessential Quintuplets S2 - 02 (Go-toubun no Hanayome S2) [English Dub] [FuniDub 1080p x264 AAC] [MKV] [CAABDEBB]’?”

The series appears to be correctly configured on Xem as far as I can tell

Any ideas?
