Storyline slides run at highspeed in preview and published.

I have a course with questions that a learner is allowed two attempts to answer correctly, when answered incorrectly on the second attempt they are redirected back to the relevant content. When back at the content they should review the content and they then have a choice to review the content again, via a button, or return to that question via another button.

The problem is that when they are redirected back to the relevant content all content from that point to the start of the question section plays at very rapid speed and then stops at the questions. 

All of my courses are designed in the same way with the same triggers, this is the only one that gives me a headache!!😊
