Navigation component not working for spawned ai's.

Ok so i have a zombie ai dynamic slice that has a navigation component attached to it. Every time i spawn it with the spawner at its spawn point location. All navigation functionally is removed. Im trying to get the navigation to work after spawning it. Also get this error whenever the entity with the nav mesh component is spawned or the nav mesh ebus is used in code. [Warning] AI: The AIBubblesSystem received a message for a non existing entity. the message will be discarded. Ty for your help.
