BuddyPress.org

Hello everyone out there!
I have a little problem that i cannot solve…

On the Profile page of any user there is no profile name above, left, right, below, or some where else of the profile picture. I would be very pleased if there would be the name like it is in the widget.
I backtraced the files where the profile is defined (bp-themes/bp-default/members/single/member-header.php and/or bp-templates/bp-legacy/buddypress/members/single/member-home.php) and in both of them there is the following code:

<h2>
  <a href="<?php bp_displayed_user_link(); ?>"><?php bp_displayed_user_fullname(); ?></a>
</h2>

but it still not shows the profile names…
can anyone help me?

greets M4lik

PS: Sorry for my not so well English. Its not my mother tongue…
