This issue was also here when iOS 7 came out or when the iOS 7 jailbreak was released, I don't remember. Anyway, it doesn't show the weather or currency traffic in my notification center. And yes, they're both enabled. I did restore my iPhone 6 from a jailbroken iPhone 5 7.0.6 backup, so that's probably the cause of the problem. Maybe resetting all settings will fix it?
