MuseSounds crescendo and dynamics are not working

Hello,
I've just downloaded MuseScore Studio and MuseSounds. It seems to me that dynamics, crescendo, diminuendo are not working properly. See the attached video, and score.
Am i doing something wrong, or is this maybe a bug?

Otherwise I'm amazed by the software and the quality of work, you guys are awesome! Huge thanks!

Best wishes,
Attila
