Couldn't find any existing threads about this and can't figure out if it is a setting.

Basically, I have a few subforums. When I post in a subforum, it's not showing up on the last poster info on the main forum page. You can have a look - https://adminloop.com/forum/ . Just posted a topic in the Forum Games section subforum (near the bottom), but it's not showing up in the last poster information for General Discussion.
