Vat (gujarat) payment in wrong period

VAT (Gujarat)

I have selected period from 01-01-2016 to 31-03-2016 instead of 01-03-2016 to 31-03-2016 at the time of online payment.

Actually party is fall under monthly category due to new registration. Registration number is taken on 15-03-2016.
he has also obtained certificate to pay lumsum tax u/s 14.

Now What ? Can I Rectify my mistake ?? Is it necessary to rectify ? Will it make any difficulty at the time of return filling ??
