Missing items in preview mode.

Any idea why I would be missing items when I go to preview?

It is form Clone of CAD Pricing "E"

If there ins't any condition that would hide a field, or any field hidden through its properties, then it could not be reflecting in the preview mode due to cache issues. Please try clearing your forms cache: https://www.jotform.com/help/229-How-to-Clear-Your-Form-Cache
