Stars Without Number Revised Character sheet not working as expected.

Hello, I am about to start running a SWN revised game. I was testing the NPC rolls out and it appears that the attack roll on the NPC tab does not work.a popup comes up to ask if the roll is burst or not. after accepting that box nothing. no roll happens. Another issue with the sheet, when an NPC type has been selected, the AC is set to 8 regardless of what appears in the NPC tab. Can you resolve the issues please or explain if i am doing something wrong in the sheet. Many thanks Ren 

I had the same issue, but I just figured it out.  You have to enter in a dice roll formula in the NPC's "Damage" field or it doesn't work.  Just type in 1d8 or whatever you need.  No parenthesis or brackets.
