It relates to some "old" existing songs with a user audio track, no editing is done.
The user audio is on the audio track.

Nothing special is done, loading the song loads the corresponding wav file but at some point the wav file has been corrupted and has saved the audio file chopping of some 1-2 bars in the beginning. Saving is done without any notification even if you just close or open another song.
In fact in one instance this has been repeated a number of times and thus ending up with a 0 byte user audio file, i.e. auido is completely lost :-(

As mentioned earlier and possibly tied to the issue is that constant numerous looping of the song gradually offsets the audio track vs the real tracks.
