Error in filing s.tax return

Dear Sir / Madam,

I have filed service tax return in Form ST-3 online and the status if showing as filed.

But there is some error flaashing in red and also it is showing in the return which I have downloaded from the site.

The error message is as under;

Following issue has been found in your return: 1.) Exemption Notification No and Serial No. is not applicable for the selected Service and/or Period of the return 030/2012-ST and 7(b) No for the service Travel agent for booking of passage (other than air/rail travel agents)

Now I want to know. How to rectify this error. Whether the filed return is valid or I have to file revise return. Kindly advice. Thank you.
