It is still unclear for me. Event logger needed to be active BEFORE you received that badge. Enabling it now (after my comment) won't fix the issue.
1. Was the event logger enabled BEFORE or AFTER you receive the badge?
2a. Have you tried recalculating the badges AFTER enabling the event logger plugin?
2b. If you already have, what was the result?
3. Was the event logger logging to a file or to the DB at the time you received the badge?
