Trouble with integration with Gravity Forms and CoursePress Pro

I am very disappointed with the integration of gravity form and CourePress Pro. Here is my problem:

I can add the gravity form shortcode into the text element and it will display correctly when the student opens the page, the form behaves as expected until the student revisits the page - then all their responses are reset (so nothing appears it the form fields) and the student can't move to the next page of the unit unless they complete the form again - and that is not desirable at all.

How do I get the responses to stay? Why won't the responses stay?
