Hierarchical Select breaks with >1 of SAME Hierarchical Select form item on the page

Hello,

I am dynamically creating a hierarchical select form using the same form function, but on call, it changes the vocab id and labels.

Here is my code for the form:

function custom_search_form($form, $vid, $labels) {
	$form = array();

	$form['hs_select_powerstar'] = array(
		'#type' => 'hierarchical_select',
		'#config' => array(
			'module' => 'hs_taxonomy',
			'params' => array(
				'vid' => $vid,
			),
			'save_lineage' => 1,
			'enforce_deepest' => 0,
			'entity_count' => 0,
			'level_labels' => array(
				'status' => 1,
				'labels' => $labels
			),

			'editability' => array(
				'status'=>0,
			),
			'resizable' => 0,
			'#required' => TRUE,
		),

	);

	$form['save'] = array(
		'#type' => 'submit',
		'#value' => t('Search'),
	);
	
	return $form;
}

Here is my form call:

	$vocabs = taxonomy_get_vocabularies(NULL);
	
	unset($vocabs[1]); // removing Acidfree Gallery Vocab
	unset($vocabs[2]); // removing Image Gallery Vocab

	/**
	Setting level labels for specific vocab ids
	*/

	// 5 is cars
	$labels[5][] = t("Choose a make");
	$labels[5][] = t("Choose a year");
	$labels[5][] = t("Choose a model");
	$labels[5][] = t("Choose an engine");
	
	// 3 is motorcycles
	$labels[3][] = t("Choose a make");
	$labels[3][] = t("Choose a year / model / engine");
	
	$x = 0;
	foreach($vocabs as $vocab_obj)
	{
		print drupal_get_form('custom_search_form', $vocab_obj->vid, $labels[$vocab_obj->vid]);
		$form_js[$vocab_obj->vid] = $x; $x++; // figuring out which vocab IDs go with which printed forms so we can implement js display/hiding
		
		
	}

Depending on the weight of the vocabulary, whichever is the top vocabulary in weight, the form values get passed. But when I submit another form, where the weight of the vocabulary (or isn't the first form output), the values do not get passed and the form state looks like this:
