Branching based on Quizmaker results broken?

I am creating a course with four sections that can be viewed in any order. At the end of each section is a quizmaker quiz. I am trying to use the 'When user passes' and 'When user fails' properties to either direct the user back to a 'Pass' slide or back to a 'Try Again' slide. The initial attempt turned off the the quizmaker pass and fail pages in favor of these powerpoint slides.

In testing, if I intentionally fail all of the quizzes, the slide that I get sent off to at the conclusion of the quiz is off by 1, incrementing by 1 with each failure. So, by the time I fail the fourth quiz, I am sent to the slide 4 slides 'down' (greater) from the slide I indicated in the quizmaker properties.

The latest attempt has been to turn back on the quizmaker pass and fail pages, but still having the properties set to direct the user to the previously mentioned 'pass' and 'fail' pages. Incidentally, these two pages are located just after their corresponding quizmaker pages. I stumbled a half-non-fix for my 'pass' results by setting the 'When user passes' property to 'Go to next slide', since the next slide happens to be the 'Pass' slide.

This is pretty clearly a bug. Is it known? Is there a fix forthcoming? Is there a workaround?

Thanks,
