I doubt that. They've removed the weekly monthly and all time pages. There are only featured, popular and recent pages now. Here you can see clearly- www.zedge.net/wallpapers/5989/sony-xperia-tx-wallpapers/ Our awards contains weekly, monthly and all time. So, it can't redirect you to such pages as they don't exist anymore so, maybe there that's why they do not appear anymore.
Again, i can't tell you the exact reason why they are not showing as i am not an admin. This is most logical reason i can think of.
The award descriptions are gone for quite a few months now. If you have noticed when you click on the awards from my account (www.zedge.net/my-account/ ) it doesn't take you to the item or even on that item's weekly page. As weekly,monthly and all time lists of wallpapers, themes and ringtones are gone from zedge now. Maybe that's why they are gone or do not appear anymore.
