Some of the field columns on submissions are empty

Hi:

I have a question: some form fields from March 15th to Febreaury 17th appears empty in my excel report. Could you tell me what was the problem? this info is very important for my company.

another detail: in the email copy apperas full of information.

Regards, 

I have the impression that you've modified this form before. Can you confirm if you've done this? Such as replacing the fields with a new one? Your 2015 submissions are blank, up until February 17, 2016. Please note that removing a field will also delete its data. I hope you didn't do this. Otherwise, we can forward this thread to our developers for them to check further. 

Hi:

i don't remember if someone modified the form. I have a copy of 2015 submissions, with no empty fields. 

I hope the developers can check it.

Regards,

I checked your form's revision history and found out that you have deleted the full name field on February 18 this year. Please take note that deleting a field also deletes its existing submissions data. This is also shown on a dialog box when you attempt to delete a field.

Unfortunately, I'm afraid there's no way to recover the deleted data anymore. You may however, find them on the submissions you received on email.
