part missing leading measures after upgrade
S2 - Critical
You had the frame Height in the parts set to -25.32sp, so I changed it to 25.32sp so you can work with it. The top margin on the main score was set to 40mm so I reset that to the more standard 10mm. I'm not sure why these were changed originally, but they are now in a state you can work with them.
So the question is how did that frame size setting happen?
