Zbrush Projection Problems Normalize

I am trying to perform this tutorial on Zbrush 4R6. I am at the beginning of part 2, but I cannot seem to project the line brush pillar features across the entire project.

I have double sided on, normalize, and deformation. I am using a scale of 2 under the Stroke palette.

Is there something I am missing?

I had this problem too, I think the solution was to enable Double under Display Properties (in the list of the right hand menu).

Thank you, that seems to have fixed the problem.
