When I utilize the "edit submission" and return to the original entry, fields that I have hidden are visible. How can this be prevented? The hidden fields are not visible on the original form.

The fields will be displayed if you're logged into your JotForm account (the form's owner), this is to make it easy for the form's owner to edit the fields even when they are hidden. 

Test the edit link while logged out or using incognito mode, if there is not a session started then the fields will remain hidden.
