Ftp user login+ hostname problem

I have a huge problem. I always use CWP and i understand it very well.
Now I have instal centos 7.0 + the new CWP pannel.
After this the problem have started.

When I create a FTP username for example: ( John ) is the username. and the domain name is : testexample.com
Normaly the username for FTP becomes John@testexample.com.

But after the new installation the system is aditing some extra information.
the domain name becomes like this  John@testexample.com@testexample.com     WHY?
Why is it puting the information 2x times the same domain.
I only put John and the system add the domain 2 times.
If you are a server admin you can please explain me this on skype: businessman_nl  I realy need to understand what to do.

HELP HELP Please

Hi,

I can confirm the same problem on my CWP servers. When you create a FTP virtual user from CWP user interface, FTP account is created with incorrect format example@domain.com@domain.com
