Often if I add a hairpin all following dynamics in the same staff disappear. What I’m doing wrong? Or is this a bug?
It looks like it could be a bug to me, but I’d need to see the project to be sure. Are all of those dynamics grouped together? If so, try ungrouping them before you add the diminuendo hairpin, then group them again.
Sorry for the late response!
Yes, the dynamics are grouped together. I sent you today by mail a little film and a project with this problem.
I had the same issue
