Greetings,

I'd suggest you contact the university for such matters because usually online portals do not have much flexibility during counselling, wrong documents, wrong category are all major issues which can cause issues later in the process

here is the link to the official contact page of the university:

and here is their telephone line:

0532-2461083

best of luck.  Great day!
