Errors on Copy and Paste
I generated 8 new bars which showed rests at the front of a melody. I copied the eight bar melody and pasted into the previous new bars. It generated a combined set of rests plus melody and altered the staves from 4/4 to say 30/16. I didn't notice this until I re-opened MuseScore 3 (in my Win 10 64-bit) next session when I saw the list of errors below.
I cannot remove the rests listed by highlighting them and pressing Delete.
How do I proceed?
I have more copy and pasting to do?
