I have disabled the Prev and Next button for all the slides. I have created a custom button to allow reset the quiz. I published the project to both html5 and flash. The flash version works perfectly fine but the issue with HTML5 version is that the "Prev" and the "Next" button would appear after revisiting the quiz (as seen in the picture). They only appear after revisit the quiz.
I am using Storyline Update 1. Is it a bug of this version or I have done something wrong.
