Thanks for your continued input Pianoleo. I think that I understood you - but look at what happens to bar one in your example i.e. nothing. That’s what was happening for me - resolved by manual entry.
Forgive me if I’m missing something - only first few days in.
If you need rests before the first note of a voice, you’ll need to use Force Duration. Set the caret to the correct voice, type O, type the number that corresponds to the note value, then type , (comma) for rest input, then Y. Much quicker to do than to describe!
