Help Needed: Follower/Following Count Discrepancy

While testing a new feature in my highlighting extension, I have noticed that I have an issue with the number of followers and the number of users I am following on Product Hunt. On my profile, it shows that I have 135 followers and am following 133 users. However, when I click to see the details, I can only see 123 profiles in each category. Has anyone else noticed such a discrepancy? Is this something normal? Or is there a way to fix it? And other question: is there anyone following me not the the list? Thanks!
