i don't know if you solved this meanwhile on your own.
If not, you can rename the tab names in the corresponding [tabname]UI.php in the /modules folder.
Right after the includes you find
public function __construct()
{
parent::__construct();
$this->_authenticationRequired = true;
$this->_moduleDirectory = 'candidates';
$this->_moduleName = 'candidates'; $this->_moduleTabText = 'Candidates';<- Here you can change the tab text
$this->_subTabs = array( 'Add Candidate => CATSUtility::getIndexName() . '?m=candidates&a=add*al=' . ACCESS_LEVEL_EDIT, <- Here you can change link texts under the tabs 'Search Candidate' => CATSUtility::getIndexName() . '?m=candidates&a=search'
);
}
