Hellfire jewelry d3 on Xbox one?

I got all the machines, I killed the bosses in the portal on t3, I bought and learned all the hellfire recipes from the merchant on act2, and finally I go to every merchant and Jeweler, and craftsman and nobody makes the ring or amulet.    What am I missing here?    It’s an Xbox one seasonal character.
