A clerical error causes wrong teenage contest winner to be crowned, error found, how should it be fixed?

A community group has a yearly contest to sell admissions to a local festival. The reward is a college scholarship and queen/king title and several parade appearances for the winner plus an 8% commission for all contestants. A queen is crowned and less than an hour later an error in addition is found and another person should have been crowned. It is decided that both should get a scholarship, the person who should have won would eventually become co-queen but in the meantime should pretend that she did not win. A week later, it is announced that there are now two queens with no other explanation on why, no acknowledgement that the second girl actually won the contest. How should this have been handled? Is the true winner justified in being upset or should she just be glad she is getting the scholarship and suck it up as the first queen says? Should the group that holds the contest do anything further or should they just "lay low"?
