Storyline course completion issue with Cornerstone in Demand

We, too, are having a similar issue with some of our courses. People complete and exit, but they still show as In Progress on their learner pages and in our reports, even though they have successfully completed and passed the course. It doesn't happen to any particular user or with any particular course. It is very random and, of course, when we try to reproduce it for our LMS to see, the courses complete as expected. I have also put multiple triggers on the Results slides to force the courses to close (an Exit button and a trigger that says Complete course/Completed/Passed when the user clicks Button 1 (Exit button) if they got a certain percent). 

We are using Adobe Learning Manager (ALM) and have contacted them. We have also sent them some of the files and they can't reproduce it either on their end. We are publishing the courses as SCORM 2004, 4th edition.
