Change Rotation in 2D while AI Move To

Hi, im trying to create a small 2D game. I use the AI move to function to let my enemies chase the player, but i also want the enemy sprite to flip on the y-axis when the player is on the right side or the left side of the enemy. My Blueprints are working at the start of the game but after that it wont update the rotation when the player is getting behind the enemys.
