DLC powers not unlocking

Hey everyone. So i just finished all the dlc content for both echoes and tides. I even did all the sidequests of tides after beating leviathan... and for what i'm reading everywhere, i should get a notification or something to go to the Arete stone and receive the Ultima powers now, but that just isn't happening... I'm going kinda crazy here. Is that reserved for Final Fantasy mode only or something? i haven't seen any mention of that, beated all the game in action mode and i have nothing left to do but go to the final boss :S help?
