Navigation in world composition?

I have the navigation system to generate only around navigation invokers. I have placed nav invokers in my AI blueprints. I have placed a nav mesh bounds in the persistent level and have none in the sub-levels. My AI will move in other worlds, but not the world composition level (big world). I do not see navigation spawning around the AI on the big world (I do have the navigation visible). Is there something I missed to get this working?

I found it. In project settings>navigation mesh: cell height. I increased that value until it worked.
