Deleted upcoming repeating meeting, but previous meetings are gone and not in deleted meetings list

[LeRoyN]

I had a series of four previous weekly meetings. I tried to add a fifth meeting to the series, but it was given a different meeting ID. I wanted to keep the same meeting ID. I tried to delete the upcoming meeting occurrence, but the entire series disappeared. The new meeting was in my Deleted Meetings list, but the four previous meetings were not. How can I get them back? And can I extend a series of meetings and keep the same meeting ID? Fortunately, the old meeting link still seems to work, so participants and I (the host) should be able to join the upcoming meeting using the old meeting link.
