Sonarr is unable to download episode - Says unknown series

[Stuke00]

Sonarr version (exact version): 2.0.0.4146
Mono version (if Sonarr is not running on Windows):
OS: UNRAID
Debug logs (posted to hastebin or similar):
Description of issue:

Sonarr will not download the episodes for this show. It is the correct episode according to the name, but the episode number is wrong. Also, I am unable to manually download it because of “unknown series”. How can I have these episodes be downloaded either automatically or manually?

Scene Naming (TVDB Naming Conflicts)

To help make things easier we've decided to setup google forms for submitting new Scene Naming exceptions. This will let us manage this a little better as well as have an easy to view list so people can check if something has already been requested. We'll update the submissions view once we have added the exception. I have setup a daily notification when a new submission is made (I'll get an email once a day), but if its been a few days and we haven't added it, please let us know here or on IRC. …

The fact that they are releasing them as split episodes (S03E18b) means Sonarr will not be able to handle the series properly as split episodes are not supported.
