Meetings disappeared from the Outlook calendar after editing

Hello,

I edited the titles of 4 recurring meetings in the Zoom client. I clicked on "Save". Since the change was not relevant for my participants, I closed the popped-up Outlook message. Now, 2 out of 4 meeting series disappeared from my Outlook calendar. However, the participants can see them in their calendars.

Can anything be done to find them? Or do I need to create new once again? In this case, the participants will get one more series of invitations...

Would appreciate your help.
