Hmmm thats very strange. They should be there above the weapons and below the Glamour Prisms. The only thing i can think of is maybe you didnt obtain the original Master book yet? Which is purchasable from the NPC accross from Talan. I forget his name but the Original master books costed 2000 gil each if im not mistaken.

If that doesnt work double check the 41-50 section. I remember noting that sometimes people recipes dont appear in the same areas. But oddly enough all 3stars should appear in the Master section except for the Furniture/Vanity items.
