Cannot match enrollments to ILT using Bulk Loader

Summary

No matter what I do, my enrollments do not sync with ILT events, tracks, sessions

Content

I use the Bulk Loader tool to set up ILT Events, tracks, and sessions. This works great. However, when I try to use the tool to create enrollments, the enrollments are not linked to the events/tracks/sessions. They are created but have no relationship to my ILT. 

Exactly what should go into the Event Name in the Enrollment template for Bulk Loader? Is it the event, track, session, or all 3? 

Please help!
