I still believe the problem is being caused by the stationing of the horizontal not matching the stations of the profile. Attached is a video showing the horizontal from 0+00 to 0+11.94, and the vertical from -2.50 to 0+09.50. It looks like the 3D element is being drawn to the elevation at station -2.5 instead of 0+00.

(Adam, your video was marked as Private when we clicked on the link. But I think the problem with stationing is also causing the cross slope to report incorrectly).
I filed a Defect (D-126542) for 3D elements being drawn incorrectly when horizontal and vertical stationing does not match.
