Country tags (why would you do this?)

[GorillaBasho]

TVDB and TMDB. Would the source be relevant, as I said the libraries have no sources selected and are set to never update, the metadata on these files was downloaded months ago. The addition of these tags was a direct result of updating Jellyfin, however I discovered today that the tags don't appear in Roku or Amazon, so only in Jellyfin media player and web-player afaik.
