Director showing up in cast list

I'm noticing a minor issue when scraping television shows from TVDB.  Sometime recently, the director of an episode started getting listed in the cast.  See this screenshot for an example.  It's episode S01E01 of Fargo, where Adam Bernstein is listed (correctly) as the Director, but also as (incorrectly) a member of the cast.  As you can see from the TVDB entry he is not a "guest star" for this episode (and he's not listed as a member of the cast for the TV series either).

I have the most updated TVDB scraper from the repository (3.0.5) and all my other Add-ons are up to date.

This is only occurring for episodes I've added recently, but it's happening consistently.  Obviously not a big deal, but just wondering what's happening and if I can "fix" it.
