JJJ:
I get the same as Noel.
I started with a "new" file and typed in your chords into the same bars as you have.
I used the mouse to click on bar 1 and drag down to bar 11 to highlight those bars.
I right click on bar 1 (the cells stay highlighted) and select Copy.
I right click on bar 12 (cells are still highlighted) and select Paste. They plunk right in there.
I tried it a few times that way, and a few times highlighting the cells and using the Copy and Paste functions on the Edit dropdown menu. Same result. It works.

Only thing different on mine is the style but I wouldn't suspect that to have any bearing on anything.
Do you think it would help if you put your song file someplace where we could get at it to do some testing?
