Notification Center center issues on the 4s

Since I got the 4s on Friday I was having issues with the Notifications Center.

First it was duplicating the calender events, then I figured out that it had something to do with iCloud.

Then today I noticed that none of the calender events were appearing in the Center, then they appeared.

Not sure what's going on. Not sure if certain settings need to be on or not. I've tried many different scenarios.

Does anyone have any thoughts?
