Pop Quiz Glitch?

To the best my knowledge this has been happening for the past few days.

When you go the pop quiz section it always shows Recently Created by default. But now it's Most Popular, while the RC is clicked.

Most Popular and Difficulty work fine - they show what they're suppose to show, but the Recently Created questions will not show up.

Is this happening to anyone else? Is it being worked on if it's an all-site kind of thing (which I assume it is).
