> Even if you change "filename.mp3" to "filename.mp4" or only change "mp3" to "mp4" the extension keeps unchanged. The result you see will be "filename.mp4.mp3".

I can confirm this, see also [here](https://community.mp3tag.de/t/datei-erweiterungen-konnen-in-der-file-liste-nicht-wie-erwartet-umbenannt-werden/70566).  
The behavour is also valid if you try to remove the extension. In my tests, it was not possible.  
@promix How do you remove the extension (please describe it step-by-step to reproduce it).
