Siri erroneously cancelled two events in calendar - no option to ignore

Without any indication why, Siri has „suggested“ that two events in my calendar some months in the future are „cancelled“. There’s no option to say the events aren’t cancelled and it doesn’t show where this information is supposed to come from. The reservations aren’t cancelled, the events should definitely stay in the (shared!) calendar. The person I’m sharing the calendar with was very upset why I cancelled the bookings - because that’s what it looks like to them. I’ve seen several posts on this site going back 4 years that report the same issue. Why hasn’t there been any fixes, Apple?
