Wrong email addres

Hi I created a Zoho Invoice account,
and no i realized that my user name has the wrong email account,
i was able to change it in the settings page of the account,

but yet when i go in Zoho Invoice, under USERS, i still seeing the wrong email address,
for each invoice i sent is being sent with the wrong address as reply address.

However i saw that i'm able to edit other users account, and change their email address.
where can i change my email address in zoho users?

Regards
