Site blocked by non-existent HTTP Gateway Policy

I have two HTTP Policies defined - both of them are currently disabled.

If I look at the Gateway Logs though, I see some sites blocked by a specific HTTP policy (Policy ID 7bcbc38e-4e8c-4bea-85b1-801e091202f7). I’m looking at the HTTP tab in Logs, so i assume this is an HTTP policy block!

Strange thing is, this Policy ID doesn’t exist in my policy list (Gateway > Policies > HTTP).

What am I missing here and why is this traffic being blocked?
