Switching Hosts for Calendars in Fluent Booking

Hello! I created calendar under my original admin login but I need to switch the host to another admin login - still me but I have two email addresses and need to separate my calendars. I cannot add a new team member either - gives me an error because it's an admin user? I'm so confused.

I need to make the calendars for Lisa Williams be under the host "Your Moxie Maven". I tried to delete the user for "jolidesigns" and just have "moxiemaven" and then it was a huge mess... calendars were a mess and now I am just lost.
