Sometimes it happens that when you are submitting the rectified form or any form because of the problem of the internet or server it might happen to shows you that form is submitted correctly but not on the administration side and as you have got officially mail from the administration so once again you should try to do the rectification

If on opening the GOAPS website and logging in it again shows same then leave it and if there is an option present to correct you should take the action. For mor details and schedule refer our website from the link
