How to fix teleportation on VR preview

I am working on a virtual tour of a school campus, and when I load into the preview I can’t teleport. I have been digging and digging but to no avail nothing can fix my problem. I tried to work with the NavMesh related settings. When I press [P] instead of showing the area everything goes white and translucent but on another level its fine. I would really appreciate help as soon as possible.
