Please tell me why the 'MoveDirectlyToward' fails in the behavior tree after I have used a normal 'MoveTo' once?

When I directly use ‘MoveDirectlyToward’ in the behavior tree, the object can move directly to the target location without considering the pathfinding. However, after I have used the regular ‘MoveTo’ once, ‘MoveDirectlyToward’ no longer allows the object to move directly without pathfinding. Why is that?
