Merlin is technically Earth-626 version of both Stephen Strange (after escaping the Garden of Eden, he uses this name), and at the same time, he is the Sorcerer Supreme in the Mystic Arts. So, Merlin should be in Stephen Strange (As he is Earth-626 counterpart of him), and be in Sorcerer Supreme because he has the title.
