Why doesn't my certificate count match between what is listed on the home screen vs the leaderboard?

There are two certificate counts that are important:

1. Your total certificate count that the leader board count. Your total count is the total number of certificates ever earned. You can see this number on the Home Screen next to the certificate icon.
2. The leader board count ONLY takes into account active content (not archived and inactivated courses).The number you see on your home screen reflects your total count of certificates.
