Zoho is automatically guessing my domain name

Zoho is automatically guessing my domain name

I own multiple domains because I run a number of websites. One domain is attached to the email I used to sign up with and Zoho Creator seems to think I want to use that domain name for this account. Wrong! I want to use another domain name. I see no place to change the domain that you want to set up with the account. 

Help!

Thank you!
