Question Changing constrained axes at runtime has no effect on multi aim constraint

Hi, I am trying to turn off the x and z axes on a multi aim constraint when the player gets within 3 units of it. My code changes the bools in the inspector, but the constraint is still being applied to all three axes. I also tried rebuilding the rig after changing the data but that had no effect. Do I need to tell the job that I changed these values or something? Thanks.

Code (CSharp):

1.         bool val = Vector3.Distance(playerPos, transform.position) > 3f;
2.         mainAimConst.data.constrainedXAxis = val;
3.         mainAimConst.data.constrainedZAxis = val;
