Why is my lockscreen showing an old event?

[Windows Central Question]

I have a Lumia 930.

In the Settings / Lock Screen / Notifications, I chose Calendar.

However in my Lock Screen, it always shows an old event like one day ago event.

I have check my date/time and Time Zone and all are correct.

This problem has been there since I bought the phone 5 months ago.

My OS version is 8.10.14157.200.

Thanks.
