Remove Staff From Project/Set hourtly rate

Remove Staff From Project/Set hourtly rate

I changed my email address over 2 months ago.  When I create a new project it shows ME as the administrator with my OLD email address.  When I attempt to change my hourly rate I get a message EMAIL ADDRESS INVALID. I cannot delete myself because I created the Project. Cannot Edit my Billing rate because the "email address is invalid." So this is obviously a bug.  I have checked user settings and have only one email address under my account but what is interesting is that my subscription payments are sent to my OLD email address also.  I KNOW selecting the "dropdown" for your login and selecting "change email id" does not solve the problem because I added this email address and it still says invalid.

How do I resolve this problem so that when I create a project based on staff hours I can change my billable hours and see the correct email address associated with my account.
