I suspect you talk about spacing in the answer area? In the Quizzing Master slides, which are used also for KC slides, you can style most text areas, with one big exception: the individual answers are not availalable in those master slides which is such a ptiy. You only have the answer area, which is the container for the individual answers, but you don't have spacing there. That means that you have indeed to change the spacing in answers manually , and space the individual answers manually as well. That is a big pain, formatting of quiz and KC slides should hopefully get some refurbishing in a next release. Please, add your voice by logging a request.
