It's not a glitch. It's a setting in the admin panel. There's this plugin that displays the threads with the latest replies. I used to administrate a forum a few years ago, but I don't remember exactly where the settings are. It's a simple fix with just a couple of clicks.
To be honest, I didn't really get into this show. I tried to watch the first episode, but I found it too confusing and I got bored somehow. Maybe it's just not for me.
