DIR-3 KYC late fee Rs.5000 asking in August?

Dear friends,

I am trying to file DIR-3 KYC on MCA site, after filling-up details it generates a challan for late fee Rs.5000.

As far as we know, last date is 30^th September, and we are filing in August, so it should not ask for late fee.

What could be wrong, please guide.
