Update: The Issue has been resolved.

Are you using an app? Is the screenshot from a moderator-only view of the modlog? Because yeah, as regular users, not moderators, using the website, we can see the actions in the modlog, but we can't see what mod performed them. In fact I remember that being an issue of contention on hexbear, some people wanting to be able to see which mod did what, but the response was that it would create too much drama if users got to see which mod removed their comments or banned them.
