I have recently found a bug that I have not come across in the forums before. I read that this would be the appropriate place to share it, so I am doing so. If this is not, I will gladly delete it.
I have found that when changing staccato/stacatissimo notes using Shift+} or just ], the dynamics written for other instruments before that start to drop down on the page. They continue to do so until they entirely disappear. I have not come across this before, and do not know if that the specific items my piece are responsible, but I thought I must share. I can also provide a video of this happening in action if needed.
Added: This happens even if I hit the button on the screen to change to staccato. Once it has shifted down, I cannot make it shift back up or undo it.
