Issue with hook_block_info

 Good day!

I'm trying to programmatically create blocks.

Here's what I'm doing in my module:

function about_block_info(){
	$blocks['about_company'] = array(
		'info' => 'About the Company',
		'status' => TRUE,
		'region' => '',
		'weight' => 0,
		'visibility' => 1,
		'cache' => DRUPAL_NO_CACHE,
	);
	
	$blocks['first_red_text_item'] = array(
		'info' => 'Popup text for the first column of the red block (homepage)',
		'status' => TRUE,
		'region' => '',
		'weight' => 0,
		'visibility' => 1,
		'cache' => DRUPAL_NO_CACHE,
	);
	
	return $blocks;
}

function about_block_configure($delta){
	$form = array();
	
	switch($delta){
	case 'about_company':
		$form['about_content_title'] = array(
			'#type' => 'textfield',
			'#title' => 'Block title on the homepage',
			'#size' => 15,
			'#description' => 'For example: "About the Company"',
			'#default_value' => variable_get('about_company_title','About the Company'),
		);
		$form['about_content_text'] = array(
			'#type' => 'textarea',
			'#title' => 'Mini text on the homepage',
			"#rows" => 5,
			"#cols" => 20,
			'#description' => 'Will be displayed as preview text on the homepage',
			'#default_value' => variable_get('about_company_text','This was the first officially registered independent educational institution in our country, which at that time was still called the USSR. It was created with the aim of training high-class professional translators, as there were no analogs of such educational institutions in the USSR at that time.'),
		);
		$form['address'] = array(
			'#type' => 'textfield',
			'#title' => 'Page address with company information',
			'#size' => 15,
			'#description' => 'For example: about',
			'#default_value' => variable_get('about_company_address','about'),
		);
		break;
	
	case 'first_red_text_item':
		$form['first_red_text'] = array(
			'#type' => 'textarea',
			'#title' => 'Text for the popup block (first column)',
			"#rows" => 5,
			"#cols" => 20,
			'#description' => 'Popup text',
			'#default_value' => variable_get('first_red_text1',''),
		);
		$form['first_red_text_address'] = array(
			'#type' => 'textfield',
			'#title' => 'Page address that the popup text refers to',
			'#size' => 15,
			'#description' => 'For example: about',
			'#default_value' => variable_get('first_red_text_address1',''),
		); 
		break; 
	
	
	
	}

	return $form;

}


function about_block_save($delta = '', $edit = array()){
	switch($delta){
		case 'about_company':	
			variable_set('about_company_title',$edit['about_content_title']);
			variable_set('about_company_text',$edit['about_content_text']);
			variable_set('about_company_address',$edit['address']);
		break;
		case 'first_red_text_item':	
			variable_set('first_red_text1',$edit['first_red_text']);
			variable_set('first_red_text_address1',$edit['first_red_text_address']);
		break; 
	}
	return;

}

:

So, in the admin panel, the block "About the Company" appears and works correctly, but the second block does not. Where is the error?
