At this stage, from above:
"Still in the quiz you have issues with (you must be in the quiz), select Question Bank, Import. Under the General selection, select the category named "Default for (QuizName)", where QuizName is the name of the quiz you have issues with - it will be at the very top of the selectable categories list.
