Hello Linda, welcome back to the forums!
Is the event a multiday event, like one that started on a past date but continues into the present date? If so, that would help explain how an event would display in the Upcoming Events list like that.
Another option is to use the “Clean-up events after” option in Events > Settings. That works specifically for recurring events and will ensure that past recurring events after a specific timeframe will be removed.
Does this help? Please let me know. ๐
Cheers!
Geoff
