[FFmpeg-user] Giving a title to an audio stream

I don't understand how ffmpeg/ffprobe manage some metadata of audio streams.
Let's take a simple example :
ffmpeg -i INPUT.mp4 -c copy -metadata:s:a:0 "title=5.1" OUTPUT.mp4
The result is :
1- ffprobe is not able to retrieve the audio title of the resulting file, whatever are the options used (I don't know if there are undocumented options)
2- VLC does retrieve the audio title correctly
3- exiftool does retrieve the audio title too
I tried to do something similar with a subtitle stream and I had the same result.
I am not a developper. Therefore I cannot read the source code. Maybe ffmpeg stores this metadata in a place where ffprobe is not able to retrieve it.
Does somebody know if this is a normal behavior ?
