Weather tracks were empty or not, it wasn't a problem in Sonar 8,5 for example. Delete Hole meant shift by whole measures no matter what. It's the measure you want to get rid off and choose what happens to events accordingly. Not all tracks have data at the same time, this is not ok
I just switched a two months ago and the workflow shows that in Bandlab you need 1 or 2 steps more to get what you want. Not very happy about it
