The episode you added is already in the "Specials" for that show. That being said, I think it is not part of the series at all, but maybe its own series as on the channel web page it is listed as series 1 episode 1.
You have removed the "web channel" from countless of Norwegian TV Shows I've added or updated.. why? When the show is produced by TV2, the main web channel is TV2 Sumo, why remove it? It makes it harder to find shows when searching from web channel, I often try to find shows in Dplay, NRK.no or others and they're always removed..?
A show can only have two channels selected (web/network) if it both airs on a simultaneously level, which I'm sure is not the case for most of the shows or any other Scandinavian channel as they have the same structure as here in my country and a few more European countries... Usually they are uploaded to those sites after it already aired on tv.
Also when a feature is implemented for web channels in our schedule (which one day will come), it will eventually be a duplicate too and require us to do some more work that is completely unnecessary at first. In case you want to find non-existing shows in our database for those channels, simply select the tv network itself?
