You dont say if the Results slide works correctly when just running it locally through a browser.
So Im going to assume that the Results slide is showing 100% score, and a PASS correctly.
If so, then test your build on Rustici's "ScormCloud"
It is the industry standard LMS for testing purposes. If it works there, then you know its something to do with your own LMS (Cornerstone).
Unfortunately I dont have any experience with Cornerstone, but certainly, some LMS can be a bit funny with certain course completion/tracking; especially when you use SCORM 2004 4th Ed.
