Conditional Continue Button

I've created a training course for my company and I have set up to provide a few slides of info, then a quiz, then more info and a quiz on that and so on. I have it set up that for each quiz, if the trainee fails, the retry button takes them back to the info so they can go through it and take the quiz again. So, if they fail, there is a trigger set on a custom made "Continue" button to be hidden if they fail and to only show the "Retry" button. If they pass, the trigger is set to hide the "Retry" button and show the "Continue" button. 

The problem is, if the trainee passes the first time, the "Continue" button shows fine. If they fail and go back through the quiz and pass, the "Continue" button just doesn't show up. The triggers are set up like this: 

Change state of "Review" to Hidden When Timeline Starts Object "Review" Results.ScorePercent is Greater Than or Equal to Results.PassPercent 

Change state of "Continue" to Hidden When Timeline Starts Object "Continue" Results.ScorePercent less than Results.PassPercent 

I even went so far to set up a trigger to make the "Continue" state Normal if the Results.ScorePercent is Greater than or Equal to Results.PassPercent

Any help would be greatly appreciated.
