### Please make sure the question is worded well enough to be understood

noticed a curious bug. No idea how long has it been there. Did not find a "bug report category for particular extractor" so will report as question. 

anyway, so here's a test link: https://www.arte.tv/de/videos/117216-007-A/tracks-east/
I run ./yt-dlp -F "https://www.arte.tv/de/videos/117216-007-A/tracks-east/"  or ./yt-dlp -J "https://www.arte.tv/de/videos/117216-007-A/tracks-east/" and noticed that for some reason Language parameter is always correct and matched the audio stream. But format_note and format will say "Deutsch [DE]"  for everything (nothing German and not).

format = VOA-STA-audio_0-Franz\U00f6sisch - audio only (Deutsch [DE])
format_note = Deutsch [DE]
language = fr

Since the audio track is French, it would be logical to say the same in format_note and format.
not a big deal for downloads, but just confusing in some cases. Apologies for being such a nerd :-)


### Provide verbose output that clearly demonstrates the problem

- [X] Run **your** yt-dlp command with **-vU** flag added (`yt-dlp -vU <your command line>`)
- [X] If using API, add `'verbose': True` to `YoutubeDL` params instead
- [X] Copy the WHOLE output (starting with `[debug] Command-line config`) and insert it below
