How can I stop TikTok from recommending my videos to people, who don't even speak the language the videos are in?

I mean I don't mind getting more views, but my language/dialect is spoken by approximately only 10 million people globally and yet according to TikTok's statistics, only about 10% of the people, who saw the videos, even speak it. It was mainly recommended in other European countries though, but that's still pointless if nobody understands it.

I already added a location to the videos, so I don't know what else to do about this!
