Why does the Kind column show the Chinese characters 文件 for Markdown files?

Finder shows the Chinese characters 文件 next the md text in the Kind column for Markdown files: Same is shown in the inspector: Through Google Translate I found that the characters 文件 mean file in Chinese. Why is Finder showing the word file in md file in Chinese? How can I revert it to English? [Here](http://s000.tinyupload.com/?file_id=19058987172706378188) I've uploaded a sample file that shows this behaviour on my machine. I'm on macOS 10.15.3, the preferred system language is English (UK). No other files show any Chinese characters. ## What I've tried Per [suggestion of bjbk](https://apple.stackexchange.com/revisions/384375/2) I've set the Open with to Visual Studio Code and restarted. This did not change the Kind column contents. Per [suggestion of WGroleau](https://apple.stackexchange.com/questions/384328/why-does-the-kind-column-show-the-chinese-characters-%e6%96%87%e4%bb%b6-for-markdown-files?noredirect=1#comment523626_384328) I checked if file README.md returned the same Chinese characters. It does not, it simply returns:

README.md: UTF-8 Unicode text

I've tried using the [mdls](https://ss64.com/osx/mdls.html) command on the file, it shows that the content type is com.unknown.md. Maybe that's can help pinpoint the issue? Full mdls output below:
