Hi Madhu,

This situation may arise due to a number of factors which is very common and can be solved without much hassle.

CASE 1: It might arise due to a technical snag in the website/ database of the website and thus in order to be sure of it, wait it out for a day and try giving in the credentials a few times to check if the discrepancy gets sorted by itself.

CASE 2: Carefully check to see if your are entering the correct details at the correct places or not, for example check the boxes whether you have to enter hall ticket number and rank or some other data and then enter carefully.

CASE 3: In case if it is none of the above then directly mail the authorities or post them a formal letter stating the discrepancy and also mention the relevant information associated to it so that they can work on it easily and humbly ask them to solve the issue and do request them expedite the matter.

BEST WISHES!
