If I display the results of a form with optional questions and some are unanswered, should I show them?

I have a page that is editable with informations about clients. It shows the questions that are answered, but not the ones unanswered. Should I show them, or is it okay to see those questions only while I'm editing the infos of the page? There is a place on the page that shows how many unanswered questions are lefts. They appears on click.
