Randomize question draw

I have multiple students working side to side on Storyline 360 modules and REALLY want my question draw to be randomized - to avert the temptation to look at someone else's answer and to prevent learning the answer by its place in questioning (they might see these questions again).

My multiple choice question quiz (used from a template) randomizes the question draw just fine, however my second quiz using hotspots does not, even though the randomize question draw is selected. What is the problem here?

Thank you, Robin
