Navigation invokers don't generate navmesh in shipping build

UE4 from source.
I am using a level with world composition on, I have a Nav bound in the Plevel covering all sublevels. I have spawn points for AI around the map and I have invokers in the AI character BP.

Everything works well in the editor, and works well if I cook for development. its only when I cook for shipping that the Navmesh stops generating around invokers, only pre-generated Navmesh is in the level after cooking for shipping.

My project was migrated from 4.21, where everything was working well.

Has anyone had this issue, No Nav error messages in logs.
Project on hold because of this issue.
