Learning Assignments - Difference Between Expiry Date and Expiration Date?

Summary:

Hello, I noticed that when a user has a course expire due to the retake settings within an initiative, the expiration date does not appear within the UI on the Course → Learners page, under the Expiry Date field (the field always appears blank even when a user has had a course assignment expire). I've also noticed within OTBI under the Learning Records Real Time Subject area, there are 2 fields, Expiry Date and Expiration Date. The Expiry Date field always appears to be blank (which matches the UI), but the Expiration Date field has the expiration dates you'd expect.
