Failed Attempt when user Exits title before Completion

We have a course authored in Lectora (SCORM 2004). The course is reporting back to the LMS a failed attempt anytime a learner begins the course but exits it before completing it. This is causing confusion with learners. The LMS is capable of allowing users to revisit an in-progress course, so this appears to be an issue with the variables we've used.

Shown in the screenshot is the same issue when we test the course using Scorm Cloud. We are using "AICC_Lesson_Status set equal to completed" and "CMI_Completion_Status set equal to passed" on the final slide in the presentation. What variable is driving this "failed" record? Should we be using a different variable? Modifying one of these differently?

Thank You! Lisa
