A graphical messup caused the wrong voting phone number to display on-screen during the performances. The show's creator, Simon Cowell, addressed the issue on Twitter.
"A lot of you noticed there were some problems with the voting numbers at the end of the show tonight...you were right," Cowell wrote.
"There was an issue so everyone has to sing their save me song live tomorrow and America will vote on that performance. It's happened once before. It's live TV. You have to deal with it, tough for the contestants though. But you have to dig deep and deliver."
The 54-year-old father-to-be added that some contestants should be thankful they get a second chance. One of those contestants is seemingly on his team.
"Now I have 24 hours to prepare my groups for tomorrow night," he wrote. "Let's hope they all deliver."
Cowell finished his rant by tweeting a precious photo of his puppy, Diddly, pleading for viewers' votes.
Please vote for Simons groups tomorrow. Love diddly. pic.twitter.com/usYUTulY1O— Simon Cowell (@SimonCowell) November 7, 2013
