Strange next event on lock screen

So on my lock screen I have this weird next event now 12AM but then when I go to my calendar nothing is in the time slot. I do use the calendar and I have had this event pop up but it disappeared after awhile. Was wondering if anyone out there has the same issue and if their is a way to get rid of it. Thanks.

To find out where this event is, when it pops up on your lock screen, go to your hub and swipe down. You will be able to see it from the HUB and edit it or delete it.
