The same format is used when Sonarr sends the request to Jackett/Prowlarr, but they translate that into a keyword search; I’m not sure what NZBGeek does. Ask NZBGeek why their API does not work with dates like this (season=year, ep=month/day), when most others seemingly do.
You might be best to try multiple other date formatted shows first, to pinpoint whether the issue is NZBGeek as a whole, or just that one show.
