Admin e-mail settings

Hello,

I need some help, I am getting the below info in the Network admin Dash board. when I installed by multisite, it asked me to set the website addresss to freewebsitedesigningindia.com instead of http://www.freewebsitedesigningindia.com but I did not find an option to do that.

Now when I am setting up my support e-mail address, its setting up correctly however as per the screenshot where wp suggests a e-mail address, it says, support@www.freewebsitedesigningindia.com in the suggestion field and I doubt it might be due to I was not able to change my domain name to freewebsitedesigningindia.com instead of http://www.freewebsitedesigningindia.com
