Articulate and SkillSoft Communication Issue

I have a course created in Articulate Presenter. It has an assessment in which the user must score at least an 80% to be considered complete in the SkillSoft LMS. Over 7,000 of our employees have not had an issue posting a passing score but now we have a select number of users (between 10-15) who either cannot post a score (LMS registers course as opened, shows amount of time in the course) but does not show a score. The score shows up as a dash (-).

SkillSoft says it's a problem with the course, based on a Java log (decoded below) pulled from one user. The user received an 80%, however, the LMS reports it as 50%.

My response to them was, how did over 7,000 people post a good score and 10-15 can't and it's the courses fault? Does nayone else have any good ammuntion to use against this sort of problem?
