brush snaps to grid on all sides except one...

I’m trying to do some very basic brush placement. I have snap to grid on and I have a brush that aligns to the grid lines on all sides except 1. Sounds like the problem described here.

I set the grid size prior to building the brushes and when I drag the brush or use ctrl+end it never aligns correctly, so I’m at a loss as to what the issue could be.
