On this page title "WP Survey And Quiz Tool - Questions" is the list of questions for the quiz. I recently added several new sections and then changed each of my 20 questions to match my desires section. However, 2 questions have disappeared, although not entirely. There is a blank row with the "edit, delete" buttons. When I delete, and choose yes. It does not delete. When I edit, it stays there blank.
I think this is the best quiz plugin I've seen and I really appreciate your development of it.
