Changing Squarespace Scheduling Default E-mail Notifications

Hi for 

www.radtalkwithtracey.com

I am the designer who built her website, so all of her scheduling e-mail notifications go to my e-mail, and there doesn't seem to be anywhere in the squarespace scheduling dashboard to change the e-mail notifications - how do I swap this out?

I need this too. i thought all administrators would receive the email notifications but that hasn't been the case. I hope there's a way to set that up.
