I am running minecraft 1.9, forge 12.16.1.1907, building bricks 1.9-2.0.4

When I try to craft any of the above stairs, or slabs I am, instead, presented with stone brick stairs or slabs. It appears that BuildingBricks' recipe for stonebrick stairs and slabs isn't over-riding the vanilla recipe. I've confirmed this in SSP and SMP both.

Prior to checking in SSP I also verified the config information matched between client and server (using default configs on both)

Let me know if I'm over-looking something or if you need more information from my side.
