Updated to Mrtk 2.2 and now realizing that I cant disable spatial mapping at the start. I can disable it on runtime, but the checkbox under `Spatial Awareness System Settings > Spatial Mesh Observer Settings > Startup Behavior` is not working.

To reproduce
------------

Set under `Spatial Awareness System Settings > Spatial Mesh Observer Settings` the value of Startup Behavior to `manual start`.
