Link to CB profile don´t work

The link to the community builder user profiles don´t work correctly in my uddeIM inbox or outbox. The strange thing is: if I´m logged in as superadmin, everything works and I get the link like this:
www.jaii.de/meinprofil/userprofile/Jasmin

But when I´m logged in as "Registered", I get the profile link like this:
www.jaii.de/mitglieder-zuletzt-eingeloggt/userprofile/Jasmin

I don´t use a SEF tool or something like this.
Any ideas what happens here?

Thank you for your support!
Michael

Did you need more information about this issue? We have no idea where we can find a solution for this problem.

Solved.
uddeIM used a CB menu item, what was located in a non public menu section.
