Save as OBJ missing polygon slider

I was trying to save a Rhino file as an OBJ but am finding the polygon popup slider missing. Is this a bug or what do I need to adjust in the program? Thanks.

Hi -

It depends on a few different things. Firstly, what type of geometry are you exporting? NURBS, SubD, or meshes? Secondly, if you are exporting NURBS, are you exporting them as NURBS or as meshes?
