When integrating A* Pathfinding, the initial steps from here are a little bit different.
Steps to setup:

If you do not have it yet, add any AStar pathfinding component to your unit game object that will be controlled for movement. Either you use a custom one, or one of these AIPath, AILerp, etc.
Then use the provided ASPFormationUnitcomponent.
Save unit prefab.
