Production Company additions declined for Series 2 of Detectorists.

The episodes for season 2 of Detectorists are produced by three production companies. I successfully added two production companies for the episodes for that season, but for some reason, I can't add 'Channel X North', as it keeps on getting denied. It says "Declined - Unable to verify.", even though I was able to add the other two production companies.
