"next slide" slides don't advance in presenter view

[incandescentman]

Somehow with org-mode updates, the "next slide" view in Presenter Notes mode no longer advances correctly. The "next slide" slide gets stuck in a loop of 4-5 slides, and just repeats those few slides. It does not reliably show you what the next slide is going to be.

I notice that the output from example.org is fairly different from the example.html that's in the repo. Something in those differences is breaking the ability of Presenter Notes to advance the next slide.

Any thoughts on how to get this working again? Thanks!
