I deleted a recurring Aero, but it's still showing up

Sometimes there's a mistake and all of the occurrences don't get deleted. Here's how to fix that:

On the My Dashboard or Manage Dashboard screen, find one of the occurrences that shouldn't be there.
Click the View button to edit it
On the Edit Aero screen, click the "More" dropdown
Choose "Edit Recurring Aero"
On the Edit Recurring Aero screen, click the Delete button. That will restart the process of deleting all the occurrences. Note that if there are a lot of occurrences, it may take a minute or two before they are all gone from the dashboard.
