Word of Mastery tracery shelf missing?

I may be missing the big flick on this, but I am trying convert to the new LI system. I have found a shelf for Word of Power, and Word of Craft traceries and I see the Heraldic Traceries shelf. I have two slots on my weapon that call for Word of Mastery traceries, yet I don't see anywhere to pick them up.

Word of Mastery traceries are on the shelves in the front room where you walk in. Each class has a separate shelf. All the other traceries are in the back room.

TU....need to open my eyes!
