Remove rests in pickup bar

Anybody know how to remove the rests in the upper staff in a pickup bar like this? edit/remove_rests doesn’t work for me. I also don’t see a feature to hide them anywhere.

Have you entered music in the next bars? Normally once you have a note (or an explicit rest) somewhere in the top staff, Remove Rests should work in the pickup bar.

thank you very much, didn’t know that.
