Challenge section does not work?

Before I saw it only took 2 hours to get the challenge like 5 days ago, however I still do not see the challenges now.  It now says I have to wait 2 days for the new challenges. Looking through the forum it seems that people are already completing the challenges. It there a way to fix this?

My challenges are now working (although some triggers don't seem to register, for example: inviting a user to my project doesn't get me a checkmark). You're best off adding an issue through the feedback button on the rightside of your Developer Profile
