Slitherine

I recently bought the bundle of all Armageddon DLC on Steam since I've really been enjoying the base campaign. Even though I have all of the DLCs set to install under library, have tried verifying files and reinstalling the whole game... when I go to the campaign options it tells me I still need to "get" all of the DLC campaigns. They are still greyed out as if I didn't purchase them. Any suggestions on how to fix this? I've never experienced this with any other purchase, Slitherine game or otherwise.
