Annotating Cross section slopes in OpenRoads Designer (Version 10.08.01.33)

I am trying to annotate cross slopes of my cross section in OpenRoads Designer. In Annotation Group Manager, the only way I could get cross slope labels to show is to filter segments by point Names and not point Feature Definitions. Even with point names not all points are captured. Even though they all have feature definitions associated with them. For example in order to label my Berm cross slope, when I choose point name of Top Back of the Curb and Face of Sidewalk it does not work. But if I choose the Top Face of Curb point name and Front of the Sidewalk it will labels it but obviously the calculated slope will be wrong. Both face and back of the curb have feature definitions which everything in them are identical, including feature symbology.

Also when I clear all filters, in order to test it, and expect to see all segments get labeled, none gets any label. I have been looking for a comprehensive documentation on the use of Expressions but have had not luck so far. Any hints would be much appreciated.
