Reoccuring Meetings missing

I am missing two reoccuring meetings that had no end date for the past 4 years and they disappeared in early 2024.  My previous invitees can still "join" the meeting and I can too with the old link but I do not have Admin rights.  I have ZERO meetings under my "Previous" meetings tab as suggested by the Community Boards.  I need to get these two meetings back and to be Admin!!
