AutoUnpack is a plugin that will automatically unrar/unzip torrent data.
This will allow Sonarr/Radarr/Lidarr to import the media files that would otherwise be ignored.

To enable AutoUnpack:
Open "Settings" by clicking the gear icon at the top
Go to "Unpack" on the left.
Check "Enable autounpacking if torrents label matches filter" and add the following:
