Hi candidate,

It's very tricky situation and it's difficult to find the exact solution as most of a depends on the officials and the verification officer how he or she handles the case.

You have to to talk with the officials in charge and explain them your problem that you had by mistake filled wrong information during the process of registration and have to ensure them with the help of your certificates that it was just an error from your side.

Rest depends on their decision. Have a good day.
