I tried to fix it...not sure why your avatar isn't showing up. I'll keep looking for a solution.
The problem is you set it as your profile picture instead of your avatar. If you are in the my settings panel, then you will see two options. One says "Edit Profile Picture" and one says "Edit Avatar" - currently you have a picture set as your profile picture, so just go back into it and go to edit avatar and then you can set that one up as well.
