The details that you wanted to update, are typed in by the center. They use the voter ID as a proof for the changed particulars.
The UIDAI does not modify any details that you enter in their website or the java application that collects biometric. If the document matches the details you entered, it updates the details in their server side. Else, it rejects the update.
This looks like a case where the center messed up. You would need to update the details again. This time, verify the details that they type, before they submit. Making sure you have a print out of the particulars before submission helps with verification.
