We would like to apologize for any inconvenience. We may need to ask you for more details about the issue you are reporting.

Can you tell us the form you've experienced the issue you described, please? I have checked your account and I have not found any form saved under it. Is the form under a different account? Also, can you give us more details about the submission that has multiple copies, please? Or, did the issue happened to multiple submissions already? Is the submission date the same for all the copies of the submission?

We will wait for your response.
