How do I remove unwanted   generated by Zend Form

After I added decorators to my Zend Form it has some unwanted  

like ->

 <dt id="step1-label">&nbsp;</dt>

My problem is, I added my form after a div in my phtml. There is a space between the div and form, I can't remove that space, can you please help me?

My complete form is

class Admin_Form_RatesForm extends Zend_Form
{
    /**
     * Form's set values and multy options
     * @var array
     */
    private $options;

    /**
     * Initailise options arrays
     * @param $options
     */
    public function __construct($options = null)
    {
        if(isset($options)){
            $this->options = $options;

        }
        parent::__construct();
        $this->setMethod('post');       
    }


    /**
     * Set form elements
     * Add elements to display groups  
     */

This is due to the DtDdWrapper decorator on your display group, specifically this code

$dtLabel = $this->getOption('dtLabel');
if( null === $dtLabel ) {
    dtLabel = ' ';
}

Try setting this option on your display group, eg

$step1 = $this->addDisplayGroup(
        array(
            'room_types', 
            'offers', 
            'insert'
        ), 'step1',
        array('dtLabel' => '')
    );

I must say, I've never liked the DtDdWrapper and honestly can't understand why Zend opted for that as default. Feel free to check out my Zend Form extension, complete with total default decorator overhaul
