Agents Colliding when I don't want them to

I have made 3D capsules and added the nav mesh agent to it. Everything is working great, but I want my capsule agents to walk through each other. I put the agents in their own layer, then I unchecked the box in the collision matrix physics editor, but they’re still pushing each other around like their still solid.

Is there something else I could do to make my capsule agents walk through each other?

Also, another issue I’m having is my capsule agents, when they hit a small bump in on the ground mesh, like walking over a wooden board, laying flat on my flat ground, the agent goes berserk and starts stuttering and moving erratically.

edit: I fixed this issue by locking my agent’s Y axis, and just having them spawn a tiny bit off the floor, but this seems like a bad fix since if I ever need them to go up slopes / stairs the end result won’t be very good. Works now though since my entire play area is perfectly flat.
