Problem with CB

Hello,

I installed SEF advance v5.2 and CB 1.0.2. Also I uploaded the sef file for CB. I created a link in main menu for CB.
However there is a problem when I try to access the registration page. I think it's due to a duplicate issue.
In reality, the url for registration in the registration CB module is:
component/option,com_comprofiler/task,registers/
The url for registration in the menu item is:
component/option,com_comprofiler/Itemid,71/ (with the message You need to login or register...)
When I turn on SEF Advance, I'm not redirected to component/option,com_comprofiler/task,registers/ (the right url to register) but to the "wrong" url component/option,com_comprofiler/Itemid,71/

Do you have a suggestion?

Thx
