Differential pair crosstalk analysis - multiboard

I am trying to carry out crosstalk analysis on 3 sets of differential pairs, going between three different boards.  I am currently using HSPICE models to simulate the connectors.


When I carry out a interactive simulation without the crosstalk option enabled, I seem to get the expected signals.



However, when I enable the crosstalk option, the results are not as expected


The top set of traces of the attached image are with crosstalk disabled & the bottom set with crosstalk enabled.


Any ideas as to why this is happening?
