I think I may have figured out what is wrong with them. The ones I get from the regular YC stores will fill a room with their scent. I burned one (from the outlet) last night and couldn't smell anything unless I had my nose right near the candle. I lit another one a couple hours ago and the same thing is happening. Darn, I thought I found a great deal, but if I can't smell them, it's not worth it.
