The first thing I would try would be a reboot.
I am puzzled as to why the camera height (3') appears to be lower than your target height (13'), and yet the view in the second image is looking down, and also why the camera is not showing up in the perspective settings plan. Are these the same view / settings or different views?
Does this happen in all 3d window modes, eg openGL shading / internal engine shading, hidden line and wireframe?
Machine / graphics card specs and AC version might help too. (I see the AC10 logo on the first image)
