Rest won't disappear after following start voice procedure

I have successfully been able to make rests disappear in a second voice by choosing “Ends Voice”. However Dorico won’t let me choose “Starts Voice” on the first note of the section.

NB This forum wouldn’t let me attach a .dorico file.

If you select the rest you want to disappear and go to Edit > Remove Rests in Write mode, does it work then?

You must zip the file first in order to attach it here.

Jan, you can attach a .dorico file. Just add .zip at the end of it’s name and it will work:
You don’t actually need to compress (zip) the file…,

Yes it does! Thank you Anja.
