My observation is that whenever the Continue button in feedback layers is placed over any choice option in the base layer, the choice hover state is caught up right after you click the Continue button. It is certainly unwanted and unexpected behavior. If you take a look at some quizzing templates in the Content Library, you will see that the Continue button in feedback layers is intentionally placed away from the choices option or it's not activating its hover state when you click the Continue button. As a temporary fix, I suggest moving the objects on feedback layers into the 'safe position' or just moving the Continue buttons a bit lower. See my attached version of your story file. Speaking of your second project, I suggest modifying and using the "Vibrance" feedback layer or moving the feedback layer buttons a bit away to avoid this issue. However, this issue/behavior should be investigated by the Articulate support.
