Different issues with the score editor of cubase 14 (drum track)

Hello, pictures are easier to undertand. anybody know if it’s “normal” and if there is a solution (that i didn’t found yet) or if it’s bugs which will be corrected in future updates ? thanks. issues are shown below.
(one capure is missing and is show belong as a link)

…but can’t help diagnose underlying causes, necessarily. What really helps the team, if you wish to oblige, is to have access to the project file itself (or a ‘dummy’ edition). You can make an attachment to a post directly (maybe zip up the file first).

yes, i can erase the tune except the parts where it’s buggy eventually.

another issue i have is when watching the score displayed while playing the song, when it’s displaying the next staff, it’s not centered, so the display show the next staff with a part of truncated. useless to use to record a part for example while sight reading it. maybe there is a parameter to check for that ?
