It takes effect on 3-3 just the Crown's sprite is bugged. Remember that Cursed Chests still spawn at random even with Crown of Curses. Easiest way to do it i'd say is unlocking the Crown for Crystal and starting with it. Or starting with whatever other Crown for the matter, obviosly of Curses being the best choice.
