Objective ID - Can you change it? (Course not marking complete)

I am publishing out two compliance courses and I'm having issues with one of them marking complete in our LMS. I built them at the same time with the same settings. I'm using the Forward clickbox on each slide to add 1 point to the overall "quiz total." And I'm using those points to tell the LMS when to mark the course complete. 

That's working as it should within one course, but not in the other. And I noticed that both courses have the same exact Objective ID in the Quiz settings. Is that an issue at all? Can it be changed?
