Sonarr version (exact version): 184.108.40.20638
Mono version (if Sonarr is not running on Windows): 220.127.116.11
Description of issue: The series American Pickers shows proper official seasons in theTVDB.com with the format of Season YYYY
Previously this is how the seasons showed up in Sonarr but recently (maybe due to the api changes) the seasons are now showing Season 1 through Season 10 instead of Season 2010 through Season 2019.

Season 2018 and 2017 were complete prior to a couple of weeks ago and I still have all the files that were previously tracked in Sonarr.
This issue is causing Sonarr to not detect newly aired episodes.
