Review Assessment "review only incorrect questions" slide properties option broken??

Hello Ben, 

Happy to help!

We're not seeing this issue being reported by our other users so there's a chance that the behavior you're experiencing is related to some existing configuration on your slide. Having custom navigation and 'hard-coded' triggers for example, might change the behavior of review mode. 

Would you be willing to share a copy of your project file here or in private by opening a support case so we can take a closer look at what's happening? We'll delete it when we're done testing!
