Hii

There is no correction facility for the final registration form. SO if you have made any mistake there is no chance of correction. Nor can you make the registration again because basic registration has been ended.
The only thing you can do is to inform the authorities of the mistake and ask them for what to do next.
Here is the contact information-

Hope this helps
Thanks!
