Retry Quiz trigger set to "Reset only incorrect questions" but also displays correctly answered questions

I'm having exactly the same experience that Laura described above...

"When I retake the quiz, and retake only the incorrectly answered questions, I also see the correctly answered questions, but not for a split second: they stay on screen until I advance to the next slide. If that next answer is also correct, I have to advance the slide again. 

Also, when retaking the quiz, once I answer an incorrectly answered question correctly, that (now) correctly answered question reappears and I have to advance to the next slide. I have to repeat this process multiple times, until the quiz finally advances to the final result."
