Thank you for asking us about this Winsteps scoring problem, Camelia.

Unobserved scoring categories can usually be resolved by adding dummy data 
records for estimation purposes, and then omitting them from the final 
reports. But it seems that this has not been effective for this dataset.

I am contacting you off-list for more details of this analysis.
