Changing character expression but not pose

Just bought Storyline 2 and have been tinkering with changing states of an illustrated character. I'm trying to change just the expression, but the pose keeps changing as well. How do I just get the expression to change?

Attached is my configuration for the Trigger Wizard. I'm using the Male 2, Worried expression, Arms crossed character and trying to change the expression to Angry. (The pose is changing to Arms in the air.)
