If I use the folowing snippet then the text adds correctly with almost no spacing underneath...
$para_nogap = array(
      'spacingBottom' => 1,
      'font'          => 'Futura Std Medium',
      'sz'            => 14,
      'color'         => '6c6241',
      'caps'          => 'on',
      'rawWordML'     => false,
    );
$docx->addText('Header Text', $para_nogap);
However if I do the same but use 'rawWordML' => true and store in a variable which I then add to the document - I seem to lose the 'spacingBottom' and it resets to 200.
