Hello Marco Ficelle,

Sorry for late reply to this,
Do you mean that you would like to hide this title "browse by profile types" right? If yes, you can remove it from this file JoomlaFolder\components\com_easysocial\themes\wireframe\users\default.php

//LINE 91 - 93

                <div class="widget-title pull-left">

                    <?php echo JText::_('COM_EASYSOCIAL_USERS_BROWSE_BY_PROFILES');?>

                </div>

If still can't, can you provide us with your Joomla backend and FTP access so we can help you check on this? Please advise.
