Maybe it was the last change at tmdb?
I only use artwork downloader with tmdb so everything is automated when I add a new title.
I never use export or nfo's because these create problems and have no interest in using a 3rd party scraper.

If you look up a title at tmdb, on the left hand side is the language tab.
English (en)

The en.png is UK.
Maybe this has something to with it?

That might be an explanation.
So far I can only tell you, no problem like yours on my side. But I'm scraping with the Universal Scraper all infos from IMDb.

If you want to take a look at your info files without exporting them from within Kodi just get this script

Install it in Kodi
Start your internet browser (i.e. Safari, Firefox) while Kodi is running
enter your lokal IP address from the machine you're running Kodi on (can be viewed in the Settings) with the port (usually :8080) like this:
123.456.7.89:8080/addons
choose XWMM
browse and edit your library info
to the top right corner is an arrow. This way you can view advanced info. In this list go to "other details" to view and change the country. Don't forget to hit save

This way you will at least know what's written into the .nfo
