Hello, Marithalie. That depends on how your Q. and A. are organized in the mindmap card.
(A) If a card has a title, the title will become the question automatically.
(B) No title but with emphasis: the emphasis is the question(cloze).
(C ) No title and no emphasis: the first excerpt is the question.
Please provide a screenshot of your Q&A if you can. It helps a lot.
Regards,
