How do I Pathfinding self obstacle

Hello,

I’ve created a family called Enemies, added pathfinding behavior, they move towards a Wheel object.

Problem: There are multiple Enemies on the screen and they follow the Wheel, but they can overlap other Enemies (be on top of each other), i want enemies to be the obsticle, so that other Enemies can go around Enemies. If i add an Enemy family obsticle, Enemies dont move. If i add solid to Enemy family behavior they don't move too.

Code:

Every 0.5 seconds = Enemies - Find path to Wheel.X, Wheel.Y

Enemies - On pathfinding found = Move along the path.
