i cannot have access to my schedule meetings that i have scheduled

Please i need help! I have scheduled recurring meetings for the season for my yoga lessons and i made the mistake to make the recurrence more specific (ex. once a week 8pm-9pm)  to SOME meetings. 

Now i can see only the ones i made specific recurrence and not the ones i clicked "no fixed time" . 

I have given the link to all my students and now i attend my own meetings with the meeting link since i cannot have access to the whole list of my meetings.

it is a big confusion to delete the meetings i cannot see.

Any chance to be able to correct that?
