Corridor Disappears When Creating Civil Cell

OpenRoads 2021 Release 2:

I've attached two files (one file for before I create the civil cell and one for after):

After Creating Civil Cell.dgnBefore Creating Civil Cell.dgn

Explanation: I have a very simple corridor that is locked to the start/end of a line with a profile. 

When I create a civil cell, using the line as a reference. The components in the 3D model disappear:

Reprocessing the corridor/civil cell does nothing. I've used various seed files and tried ORD 2020 Releases with the same result.

Please let me know if you have any suggestions,
