Quiz review only displays for a few seconds.

I have a timed quiz which after 30 minutes ends the quiz and sends the user to the results slide.

On the results slide I have the option to review answers or retake the quiz. 

Selecting either of these options results the expected page opening (either review or retry) but closing after about 2 seconds.

I am assuming it is to do with exiting out of the quiz without finishing it, is there a workaround?

I am not using the default storyline timer as the client didn't like it.

For the timer I just have it dumping out to the results page after a manual countdown reaches 0.

 

I am sure there are better ways of doing this (that work!)

 

Many thanks in advance
