Update. Found out that my wife had unchecked “Event” Category and updated the Posting date. (I reuse the Event’s post as a regular post for covering the event but if it’s going to screw up this badly I won’t be). I’ve even tried deleting the entire post and to no avail. I have the same event appearing on my calendar from Oct. 2 through the 31st even though the event was only supposed to appear on the 2nd.
