Storyline Quiz Review - Is the Incorrect/Correct message editable?

I have hidden slide navigation buttons throughout my course, but when  I go to review the quiz material, I have added  a player trigger response- when I remove the slides from my project all works fine, but within the project the previous and next buttons do not appear in the review process.

What have I done wrong?

Here is the question slide

 It has my submit botton

But when I review the question- no slide navigation buttons apper in the project

 but if I cut and past the question slides and quiz review slides into a seperate articulate project the slide navigation buttons appear in the review

 I want these sldie navigation buttons to apper in my actual project and wonder what I've set wrong to cause this problem.

Any ideas?

Here are my slide trigger details for the project where the review slide navigation buttons don't appear(not working correctly)

 And the new project where it works fine

 any ideas?
