Boardsim differential via modelling

In Boardsim v8.1.1, when I export  a differential net to free form schematic, it seems to ignore differential vias and just export two independent vias. I wonder how accurate is this method?


From Boardsim user reference document, it mentions a Via Model Extractor Wizard, which can be accessed through "Select Export > Signal-Via Model and select the Select Signal Via page", and can do differential via model extraction. However, that option is greyed out in the menu of my BoardSim v8.1.1. Anybody knows what is wrong?
