WP Admin Users area reporting more admins than there are

In my WordPress backend, the Users list is saying Admins (3). I’m the only admin on the site. If I click that link to only show admins, it only shows me. In the database, I don’t see any additionally listed users (I have 9 users altogether, 8 are subscribers, 1 is me, the admin).

Any idea what might be happening here? I was worried about a hack…but since the db isn’t reporting any additional users either, now I’m wondering why it’s reporting that number at all.
