Geometry in Hover Heads Up Corridor Display Disappears

Has anyone else come across this issue? There is nothing wrong with the corridor according to civil display browser and the corridor is following all geometry and constraints. All reference links are present. A corridor reattach was tried to see if that would bring names back, but no luck. Software is PowerGEOPAK SS4.

And no, we can't upgrade to ORD due to contract requirements, so any other guidance or input would be greatly appreciated.
