In some series - for example My Hero Academia - Sonarr only returns one search result for episodes. Often they are Japanese and rejected, rightly, for download.
However, if I go to nzbfinder and search for the same episode manual, it returns several results.
For example, Season 2 Episode 2 finds one japanese result in Sonarr but 12 different results if I search manually on nzbfinder.
I’ve checked the categories in the Sonarr setup and it is including the same categories as the manual results
