Sorry about that! Tried to take a short cut with a Duplicator plugin for the Events Quiz and this tells me that the plugin does not work completely with LearnDash Quizzes. I’ve fixed the problem and you should see just the DOM questions now!
There is still some wonkiness going on, though. Two RGB questions. And Two, “Which method will allow you to save the removed node as a variable?” questions which is marked as correct the first time it’s shown if you select removeChild(), and remove() the second time around.
