When I try to edit the measure and tap on the number, a totally random non related measure appears and I cannot edit what I wanted in the first place. 
You can move move the labels by dragging them, does that help?
Actually, no, it does not help. I tried doing that, but again when I move to the value that I want to change, a random other measure appear again over the one I wanted to change in the first place
Can you send me the workspace to istvan@shapr3d.com?
