Accuracy Issue with Roadway Designer cross sections versus Draw Cross Sections from DTM

An issue came in today that I think will benefit the community to see troubleshooting techniques as we work toward a resolution.

We are seeing discrepancies in some cases between what the modeler will show as a point offset value (or elevation) and what the cross section will show for the same point.  The settings we are using are to 4 decimal places, so the delta may be 14.5708 in the modeler and 14.5715 in the cross section.  Is there any known issue similar to this?
