Change the Appointments+ Admin email

I have tried several things to change the admin email, including setting up several email accounts for each separate service provider. I removed “admin” from the site altogether and still only get emails to the admin email account. I’ve gone through the database and don’t see a reference anywhere to the email that keeps getting all the confirmations. I even changed the global “super admin” email address, thinking the plugin might just be emailing the global admin (not so). So now there is no reference (that I can find) to the original admin email ( but all the confirmation emails still go there. The providers don’t get emails either, only the xxx email. I should note, the people making appointments do get confirmation emails. I have also dumped the server cache, rebooted Apache and MySQL services. Emails still go to the original xxx address and no providers??? Any help, pointers?
