Wrong number of followers displayed

Hello,

on my blog (hosted by WordPress), the following is displayed: “You are following this blog, along with 275 other amazing people.”

When I go to the admin menu, however, I see that I’ve got only 29 followers (16 WordPress.com followers and 13 Email-only followers).

I did not connect to any social media accounts via Publicize, meaning that under “Sharing”, no social media account is connected.

Why is there this discrepancy in terms of follower numbers, and how can I access the 275 followers (if they exist)?

Thanks,

Daniel
