Why are students that were exited from Infinite Campus in Term 1 still showing as enrolled in the Canvas Term 2 classes?

We use the OneRoster API to synchronize our Infinite Campus data with Canvas. The nightly synchronization process is running successfully and has been all year. Unfortunately, a student that exited the district at the end of Term 1 is still showing as enrolled in his Term 2 classes in Canvas. I made sure he had an end date on his enrollment and courses in Infinite Campus. The only issue that I see possibly causing an issue with Canvas is that the student's drop date for the Term 2 class is before the start date for Term 2. Everything else looks fine.

We are having the same issue. We are also seeing students get added to courses that they are not scheduled in. 

Infinite Campus states that even if the student is deleted without an end date, they are excluded from the "magical" OneRoster export.
