Zoom Meetings Linking to wrong calendar

Hi - 

Up until recently, when I scheduled a Zoom meeting, it synched directly to my Google calendar.  Suddenly it started linking to my Outlook calendar (which is just used for a specific client.)

I've tried linking it to Google again, but it doesn't allow me to do so.  Is there someway to UNLINK everything and start fresh?  This seems simple, but I've tried lots of different things and it's not working.

Thanks,
