Gradual dynamics playback

Hello! I imported a musicxml from Cubase, deleted all automations and entered dynamics to passagge. Somehow, dorico doesn’t play back cresch and diminuendos gradually, but changes dynamics very suddenly, where the dynamic markings are. If i enter a new passagge to dorico with dynamics, it plays back normally. What should i do?

I discovered that i see CC1 data and i cannot delete it

It sounds as if you might have the wrong expression map assigned to the instrument, so Dorico doesn’t know how to play back the dynamics. What playback template are you using? Have you made any manual sound assignments in VST instruments, or changed the expression map assignments yourself?
