Player AI movement animation

Following Behaviour Tree Tutorial I created required blueprints for AI movement. It moves fine.
However I’ve got animation blueprint for my AI character which relies on boolean values to change states.

For example for switching to movement I check where isMoving variable is set. (it is marked as editable)
To set it I added this to RapidMoveTo task

But during gameplay I does not change the state! The enemy is moving in its idle state towards my position. What is the problem?
