Can't use Navmesh Obstacle on AI?

I'm having trouble with AI bumping into each other and getting stuck, so I tried adding a Navmesh Obstacle component to them so they'd avoid each other.

But it just causes them to slide all over the place. I'm assuming its because the AI is trying to avoid its own Navmesh Obstacle. Is it possible to tell an AI to ignore his own Navmesh Obstacle and only react to the other AIs'?
