Station Offest Annotation doesn't work ?

Recently the ICT department finally installed PowerRailTrack B8i SS4 (08.11.09.845) on my system. Everything seems to work OK, but I have an issue with the StationOffsetAnnotation. I use this quite a lot to check the distance between alignments: existing to new or between two new ones - with an annotation every 2 of 5 meter. This worked fine in SS2, but not in SS4. I use the same settings (station offset, select two alignments and an interval) and for the annotation Offset and Delta Elevation.

In SS2 this produced leaders with de distance and height difference between the two specified alignments.

In SS4 however the height difference still works, but the distance stays zero. Using a report does work fine, so there really is a distance between the alignments. But with annotation, no matter which combination of alignments, to or from - the distance stays zero.

Am I doing something wrong, or have I encounterd a bug ?
