The full translation's up now, but it's essentially that the Venom Sword's power can only be used once per individual unless you allow yourself to be "swayed" (contracted) to the demon. So in essence, while Carlos was under the impression his face could be changed back, it apparently couldn't have unless the demon and him worked something out.

Same with Mayrana. She wanted a specific face and Magician could've easily given it to her, but she wanted to spite Mayrana so gave her face with slight differentiations that only Mayrana would fly off the handle about, which Magician finds amusing and fitting for the jealous Julia fanatic. Of course, she would never tell Mayrana this; she'd much rather play to her haughty personality and admit how "inferior" she is and so must've messsed up.
