I would firstly advise you that their is no need of getting worried , they also understand applications are very large in number and their is probability of mistakes by some students which has not done intentionally. They will not reject your application for sure for which you just need to write an email to the authorities about the mistake which you have done as a undertaking so that they can know that you havent done it intentionally

Hope you found this answer helpful. Good luck for your future
