Pathfinding Issue - No navigation mesh

Hi there, I’m attempting to use a K9 dog unit for a game I’m developing for and the navigation meshes for Studio doesn’t seem to want to render for this map. I’ve moved the K9 and the scripts involved to a separate game and the navigation meshes are rendering just fine.

Here is an image of the map (with navigation meshes & labels on):

Any help or ideas as to why this could be happening are appreciated.
