Submit different answer option does not allow fields to be edited

We saw an issue with CoursePress Pro plugin. On Course pages, there is a button to save answers on questionnaires and exit (so the answers get saved when you get back to the pages). When pressing the "Submit different answer" link on the Unit pages (screenshot): http://i.imgur.com/VylyWXM.jpg

We are able to edit the answers on the checkboxes, but not on input fields: http://i.imgur.com/i6aurvi.jpg

Is it possible to make it editable like the checkboxes when the "Submit different answer" link is clicked?
