Can not change profile name to same as at DCS main page

[Iku_CC]

Howdy,

 

I changed my profile name at DCS main page. So I thought I can do the same here at forum. But when I try save my changes I get error message "Email addresses must match"...even if I have correct email at both fields.

So is this possible to do and if so..why I can't do it?
