In BE Flexform you can set header and message for Logout but in the showLogout function use status values

#14334
$markerArray['###STATUS_HEADER###'] = $this->getDisplayText('status_header',$this->conf['logoutHeader_stdWrap.']);
$markerArray['###STATUS_MESSAGE###']=$this->getDisplayText('status_message',$this->conf['logoutMessage_stdWrap.']);$this->cObj->stdWrap($this->flexFormValue('message','s_status'),$this->conf['logoutMessage_stdWrap.']);

should be
$markerArray['###STATUS_HEADER###'] = $this->getDisplayText('logout_header',$this->conf['logoutHeader_stdWrap.']);
$markerArray['###STATUS_MESSAGE###']=$this->getDisplayText('logout_message',$this->conf['logoutMessage_stdWrap.']);$this->cObj->stdWrap($this->flexFormValue('message','s_status'),$this->conf['logoutMessage_stdWrap.']);
