Old missed calls notfication issue

[Joeyy]

Hello
After I delete all my call log, it's shows me missed calls from 100 days ago(!)
WHAT to do? I've deleted already twice all the call log - still after an hour it's
show me once again the old calls ?

Start by restarting the phone. Hold both the home button and the lock button down together until the Apple logo appears, then release. A simple restart cures most wonkiness.

I've seen this after restoring and setting up as new which is all the more bizarre. Hours (or even a day or two) later I'll start getting four or five missed call notifications at a time.
