Viewers can vote over the phone or by pressing the red button on their televisions to determine which famous contestant will leave the show.
However some of the votes from Sunday night's programme were not counted towards the final vote.
A full refund is being offered and a donation will be made to charity.
Football player Dean Holdsworth, who was voted off the show, has been reinstated.
A spokesman said: "Sky is taking immediate action to remedy the situation. nWe would like to apologise to our viewers."
The show, which is broadcast on Sunday evenings, is presented by Jenni Falconer.
Twelve celebrities, which include pop stars Ritchie Neville and Shane Lynch, are competing by learning various circus tricks and performing them in a ring in front of a live audience.
