Chinese characters in Mac Finder file Kind for markdown files

For some reason I have Chinese characters to the right of “md” in file Kind in Finder.

Even if I change the extension to .markdown they remain in the info panel for the file.

I’ve tried changing the region, and even reinstalling macOS.

I would be very grateful for any suggestions as to how to remove these characters or at least know why they have appeared!

There’s a pattern

Maybe Bear is mixing up its regionalization?

I don’t have Bear installed, but it may have coincided with installing LaTeX tools.

Would EtreCheck help to identify this do you think?

I’m not sure. I’ve only recently discovered EtreCheck. It wouldn’t hurt to run it and see what it finds.
