Strange artefacts when using R to repeat passage

I have an 8-bar passage of simple piano music which I want to appear identically twice in succession. I input the first 8 bars, then marquee-select the passage and hit R for Repeat. This has produced strange artefacts, including spurious rests, a misplaced voice 2 note and a misplaced hairpin.

I thought it might be something to do with the start/end voice properties of the voice 2 note in the original passage, but fiddling with these makes no difference.

Can anyone advise what I’m doing wrong?

Thanks in advance!

This is caused by a bug, I’m afraid: there is a problem in handling selections where one voice starts at a later point than the others in the selection, and so it gets offset incorrectly when pasted. We’ve already fixed this problem in advance of the first update, so this should be much better soon.

Thanks for your very speedy reply!
