Pre Registration Form Export To Csv Is Blank

I have been dabbling with the Pre Registration form and it looks like a winner. However when I try to export the data the CSV is empty. Please refer to the screen shot of my test data.

I am wanting the students class and name, along with the parents email address, so I can match the email to the students photos, then generate passcodes within the system. However at present the CSV is completely empty. I have tried opening in Excel, Libre Office and a plaint and pure text editor. ll i see are the column headers and none of the data.

What am I doing wrong?

I am ohping to have this working for a shoot in 3 weeks time

Thank you

Something I have fixed for the next update. Send me an email so I can reply back with a file attached to upload to fix it.
