Description of issue:
sonarr doesn’t search japanese name for anime. Xem shows that attack on titan has another name: Shingeki no Kyojin but sonarr doesn’t search it

Sonar Version: 2.0.0.5344
Mono Version: 5.20.1.34
OS: Proxmox > lxc container > docker > hotio/sonarr

I have the same problem but on Sonarr v2. Happens for me with Laid-Back Camp (Yuru Camp). Xem shows alternate names but Sonarr only searches for the english name. Of course I get some results but because most torrents for this show are available under the original name I won’t get the results I’m looking for (in this case the x265 releases). Already tried manually refreshing the series, running some tasks manually, removing and adding the series again. It also does not show an alias as a tag. Chaning the series type from anime to standard and back shows that it is doing something with xem, at least for the episode numbers.
