OK, I did some tests, and here is the result.

1. Go to chord sheet, select a range.
(Chord sheet selection is always the fastest and easiest)

2. Right click in chord sheet and copy, will copy the chords.
Alt+F8 window copy button, will copy the audio.

3. Click a bar in the chord sheet, or a position in the AEW.

4. Right click in chord sheet and paste, will paste the chords.
Right click in AEW and paste, will paste the audio.

5. Try not to use Ctrl+c or Ctrl+v, in either situation.
It's confusing and tend to copy the wrong thing.
