NavMesh and Navigation?

No matter what i try NavMesh Volumes do not Generate a Navagation Area or any data The area stays blank no green/red zones, Nor do any behaviour trees or Dino AIs refrence a navigation but their AI just send them in a straight line towards their target and on collision it runs a Move Around Blockade action in the DinoBT?, Has NavMesh Functionality really been removed?

Come on Devs need a answer to this Without it, My game mode is useless and i rather not waste time try to Achive something that i cant at this point? Cheers.
