SCORM2004 tracking in SAP SuccessFactors

I have a long course (60 mins) and our SAP SuccessFactors LMS stops updating suspend_data (bookmarks) at a certain point. I tried SCORM2004 4th Edition because that can store up to 64,000 characters as compared to SCORM1.2 which is limited to 4,000. While this fixes the bookmarking, I discovered SuccessFactors won't track completion even though the Complete Course trigger is in place in the course.

Does anyone have any experience with SCORM2004 tracking with SAP SuccessFactors LMS?
