But it looks like a fake mistake.
Maybe the 3 are acting out a pre-arranged script.
The financial backers of the contest wanted something sensational to get into the news?
Otherwise it is just another contest that will never be known and never make it onto the prime time news, right?
Common sense tells you that such contests e.g. Miss Universe, Miss World, etc have been around long enough for people to know how to have the SOP to prevent this highly foreseeable boo-boo.
