The following is copy and pasted from the FAQ:
Sonarr grabbed a release, why can’t it import it?
The reason it was able to grab the release in the first place was because the indexer returned the tv rage ID for the series and Sonarr was able to match it to that, but that ID is not available during import, so it fails.
So for whatever reason, sonarr went out on it’s own and downloaded special episodes for 2 different TV series. The downloads are sitting the folder waiting to be processed, but sonarr won’t process them.
What is the solution to the FAQ post I quoted?
Possibly, but specials are unique in that they are usually poorly named. I expect here that the file name is even worse than the release name and Sonarr can’t understand it.
If you post some debug logs we can take a look, otherwise you can rename them to S00Exx and let Sonarr import them from the Drone Factory.
Okay, I think I figured out a few things:
- I needed to set the log level to ‘debug’ in Settings>General
- System>Tasks>Downloaded Episodes Scan - rescans the drone folder
The file names of the files in question are in the following format:
name.of.series.title.of.episode.720p.hdtv.mkv
edit: removed logs.
Thats why I said debug logs 
Those are what I expected, just rename them to Series.title.S00eXX.720p.mkv and move them out of the folders, or rename the file and the folder.
XX = the episode number, which you can find in the UI.
I’ll try to add some testing around these cases, but its not something I’ll be able to look at soon.
Already renamed them. I actually had to rename the folder name as well to match the filename, or it wouldn’t process the contents of the folders.
But it worked. At least I learned a few things about Sonarr today; thanks for the help!
