OpenBridge Modeler Bearing Seats Floating Above Crosshead

When modeling bearings with seats and tapered plates I have noted that at some locations the bearing seats seem to float above the top of the crosshead.  Does anyone know if this is just a graphical issue and the heights of the bearing seats are being calculated correctly or is there an error in the calculation of the heights of the bearing seats?

The image below shows the bearing seat floating above the crosshead.
