Minimal surface - mesh normals inconsistent

I’ve created a minimal surface from these 3 planer NURBS surfaces where the surface normals are pointing out.

But when I create a minimal surface I get the following when I bake it - 3/4 of the triangles are pointing in.

Why does this occur?

I’m using v2.50 of Kangaroo.

Your initial mesh needs to be unified it’s normal directions.
