My Previous Meetings Have All Disappeared

I have several Zoom meetings which occur on a weekly basis, and when I noticed that I was nearing the links' expiry dates, I opened the Previous Meetings tab and tried to extend all of them by clicking "Edit All Occurrences" and setting the deadline ahead by another month...but in doing so I apparently eliminated any trace of the previous meetings associated with each of those links (and that's a problem, as I use that information to cross-reference my payment invoices and other documents associated with my work). Is there any way of recovering this lost information? Does Zoom store it somewhere?
