Get Random Reachable Point Issue

In the default character test level either Get Random Reachable Point in Radius or Get Random Point in navigable Radius both work fine.

When I run the same BP on my game level which uses Landscape the functions always fail (return value is false, returns 0.0.0 as a location).

Paths are fine (shows green when press P) and AI will perform other navigation tasks I use indicating they can walk around based on specific locations I assign.

Any suggestions other than deleting all nav meshes and add just 1, adjust the radius to various sizes, stop/start editor as I tried these and can’t get it to work.

Thanks.
