Ramdom Profile URL pro problem. (joomla 3 with community builder) (i can give you all admin acess by mail)

Hello, I have an problem with profile URL pro for community builder.Indeed, the profil url pro like domain/username are not available from userlist always. It's shown profile URL PRO sometime, then community builder URL another time.
For an e.g, when you access to this user page the link is long :
http://www.airfrance[...]rprofile/ADEFLY
But for this user the link is short as profil URL pro :
http://www.airfrance[...]tuel.com/afr038
At the same time, profile URL pro replace all Captal letter to small letter, and remove space on username.
