Each of your fields have a Field ID, which is how Ragic identifies and references to your fields. In some cases you might need to manually edit the Field ID. Please note that manually editing the Field ID is in beta, so use at your own risk.
To manually edit the Field ID, navigate to the Design Mode, and focus on the field that you'd like to edit. Double-click on the Field ID number below the Field Name. A window will prompt you to enter the new Field ID number.
If you accidentally deleted a field from your form, but the field and values are still in the listing page, you can add this field back to your form page.
