Blank Forms coming in

We have gotten a couple of submission in the past few days that are coming in blank on the form page but we have the information showing up in the email however it shouldn't show us the signatures in the email. Can you tell me what the problem is?

We are truly sorry for the inconvenience caused. We had a data replication issue between our servers recently but it should be fixed now. You should now be able to see your form submissions data.

Regards
