Collision inconsistently responding to pawn collision

Actors utilizing overlap or ignore collision for the pawn collision channel are inconsistently responding to pawn actors. In some levels the overlap works correctly, in others, the pawn is blocked by the same object.

Note: It appears the Pawn is blocked as long as the PhysicsBody collision channel is set to block, even if the pawn is set to no physics body or no collision.
