Reach360: Course incorrectly showing as complete

Have published a quiz to Reach360 that has been created in Adobe Captivate. Quiz plays correctly and the score is tracking accurately into Reach, but course is showing as complete irrespective of the reported score (i.e. learner fails the quiz, but course still shows as complete, in the attached example a score of 80% is required to pass/complete.)  

I can't find the option for setting completion requirement - for a Rise or Storyline file there is an option to set this in the course settings, but this option is missing for an imported course. 

Any ideas on how to fix this?
