Exported Calendar ics file - shows deleted data??

I am exporting a custom birthday file from Calendar app to import into Lulu.com as am creating a photo calendar with birthdays for 2024. Lulu.com shows an error in importing, so I checked the file...To my huge surprise and dismay, looking at the created .ics file in BBEdit shows data from years past which has been deleted. It also shows some names with a middle name, and all my birthday and anniversary events in Calendar just show first name and last name. Perhaps middle names were entered when I first used the app...

I am flummoxed as to how to only export current events. I have been using various versions of the calendar app since it's inception, as am a long time Mac user.

I just need the birthdays and anniversaries which are entered in the calendar as yearly recurring events. As people have died, etc., the entries for future events for that person are deleted. If I search for one of the errant entries on my Mac, nothing shows, but the entry is still in the .ics export...

The following is an excerpt showing two events with two long deceased events. How can I get Calendar to just export current data?
