A* Pathfinding is not working with only one animator

Hello everyone, I already created 4 types of enemys in my game. Every enemy have animator component, AIPath and AIDestinationSetter. Everything is set to 2D. When I created fifth type of enemy, object didn't move. I discovered that when I switch animator controller in Animator component, AIPath statring working correctly and object is moving. I created new objects with animators and everything was working fine. So it is not working only with one animator. I don't have idea why. Can you help me?
