Lesson_Location not sent to LMS

I have a course (SCORM 1.2) that is not passing this lesson_location to the LMS. As a result, the LMS progress bar is not working. The course has a post-test. This score is sent to the LMS. If I fail, I don't receive a certificate. If I pass the test, I get the certificate. Again, the only issue I'm seeing is the progress bar. 

I see the same behavior in SCORMCloud.

Any ideas that I can test? 

I appreciate it.
