So Im populating the monsters sheets for my game on sunday, and while checking to make sure everything is set up correctly I used my trip/bite buttons on the attack tab. I got a "Input Value; Attack Modifier" popup. I had it set for "CMB + - + ____" vs "CMD" then I changed it to " - + - + 11" vs "CMD" for trip and "melee + - + 2" vs "AC" and changed it to " - + - + 12" vs "AC" and I got the same popup for both ways. I went to another character sheet of my players and the roll went through fine as done on theirs. Not sure what's going on.
