ORD Transverse Feature Reports - how do I get feature elevations?

I want to generate a report that lists the offset & elevation of a handful of 3d features at regular station intervals. In InRoads SS2, I would do this by running a Station Base Report on my active horizontal & selected features from a DTM. When the XML viewer pops up, I switch to the Transverse Features Report and that's it.

I'm not able to get the TF Report to work in ORD. I can get the TF Report to populate by running a Station Base Report, but the elevations are the same for all features and appear to represent the elevation at the geometry line. I've tried this with features associated with a corridor and 3d features drawn manually, all with the same result.

What am I missing? How do I get the elevations to equal the elevation at the feature?
