Consecutive Hot Object Interactions in quiz won't reset

Can someone help out with a “what should be fairly simple” problem I am having with the quiz template.

I have a 5 frame quiz that I’ve developed from the template. All 5 interactions are Hot Object interaction types. The problem I am having is when I go from one frame to the next, the Hot Objects do not reset. Whatever the selection from the previous slide was, remains in a selected state.

I’ve tried renaming the Interactions in the Component Inspector, but that doesn’t work. If I put some other interaction between two Hot Object Interactions, no problem. It’s only when they are consecutive.

Can a Quiz Template guru please help?
