Prevent a question from be randomly selected twice from a question

After days of tearing my hair out, I wish I never embarked on using the branching option in Storyline 2. There appears to be no way to guarantee questions will not be repeated. If the order is locked, Storyline takes the first question from the locked selection and plays it over and over. The only way to stop it is by not randomising the questions in the bank and put a different question at the top of each draw slide...to which I wonder why not just have the actual question slide rather than having banks at all?

This feature causes more frustration than value. I suggest removing this feature until it is functional. What quiz taker expects to reattempt a quiz question several times in one sitting?!
