Post review slides not working properly

Hello Nadia, 

Thanks for reaching out!

As a troubleshooting step, try setting the revisit behavior of your question slides to Resume saved state so your question slides do not reset your learner's responses when they revisit the slides for review. 

If this doesn't work, would you be willing to share a copy of your project file here or in private by opening a support case so I can check how your question slides are configured? We'll delete it when we're done testing!
