Print Dialog only shows 1 paper size

[V8i]

I have defined my paper sizes in printer.pltcfg (ANSI A and ANSI B) and set the default to ANSI B.

       

When I try to print, the print dialog only has the first paper size (ANSI A) in the list as an available choice. If I move ANSI B to the top of the "Define paper sizes" list then it will be the only option in the print dialog. Why is the print dialog only displaying the first paper size of the list?

        

Thanks for any help
