Cubase 15 score editor dynamics not reflect dynamics in midi?

I start using Cubase Score Editor and tried dynamics. They are supper snappy but when i tried crescendo and decrescendo hairpins, it allways jump strangely and sometimes it does copies of last dynamic sign.

And main problem, they are not shown in midi? Why not? If I add in midi editor dynamics they are shown in score editor, and they are twice here because once I added via score editor and second added via midi editor. I think this is also bug.
