Quiz not returning to initial state

Hi Maria, thanks so much for your help.

Here's what I'm going for. I want the user to click the (submit) button after the audio is complete and when the user gets the answer incorrect, to return to the base layer without replaying the audio. That's done. I want to enable the submit button to run normally when the student returns to the slide. that seems to be working 

What's not working is when the user goes back to the slide, the quiz has not reset to its initial state, so the user can't re-do the quiz.  Of course, I set it to reset to the initial state and made sure the user had multiple tries with the question.   SO, what am I doing incorrectly that quiz won't reset?
