Character doesn't move at all

I have NavMesh, Mixamo character and AI class inherited from AIController. I have tried “simple move” and “move to” nodes, but it doesn’t walk.I have tried another character, not by Mixamo, it also doesn’t walk. I have tried to make it walk with behavior tree, also unwalkable. UE 4.7.4, not from GItHub. This is not controlled directly by player, the game is RTS. Here are screenshots of details of AI and character. What I do wrong?
