Bug - BUG: TVDB scrapper doesn't retrieve latest json.

Hi,

I've encountered the problem. 
This is the json feed which TVDB queries - https://api.tmdb.org/3/movie/444218?api_...uage=en-EN
from that feed its clearly seen that production contries data are supplied:

However TMDB provides old outdated json feed, which you can preserve from its cached file
~\AppData\Roaming\Kodi\cache\scrapers\metadata.themoviedb.org

Here is the content:


Therefore when movie is added to my library, I cannot filter movie by Countries, which is quite important for me.
Can you please advise?

Thank you.

UPDATE:
Ok, I've identified where the problem lays:
KODI does the query https://api.tmdb.org/3/movie/444218?api_...anguage=ru instead of supplying full Language culture, it should be really https://api.tmdb.org/3/movie/444218?api_...uage=ru-RU 
so Language is ru-RU and not just ru, any reason why addon is not supplying full culture language information?
