Can't remove alert

I have 1 alert that cannot be removed

Is there anyway to fix it?

Yes, I had this same problem. Click on the alerts and click view Alerts at the bottom and then it takes you to a screen where there is a delete option on the side and just delete all the alerts that are recent and it will go away.

Thanks guys deleted the alert and it worked
