Meta Box

I suppose there's something wrong with image_advanced field in nested groups.
I tried to exclude nested group, so for now my metabox looks like:

// Group
			array(
            'name' => 'Сектор инфраструктуры',
            'id'               => "{$prefix}sector",
            'type' => 'group',
            'clone'  => true,
			'sort_clone' => false,
            'fields' => array(
	            
	            
	            
	            array(
				'name' => __( 'Название сектора', 'rw_' ),
				
				'id'   => "{$prefix}sector-title",
				'type' => 'textarea',
				'cols' => 10,
				'rows' => 1,
				
				),
				
				array(
						'name' => __( 'Описание сектора', 'rw_' ),
						'id'   => "{$prefix}sector-description",
						'type' => 'textarea',
						'cols' => 10,
						'rows' => 4,
						),
				
					
				
	            array(
						'name'             => __( 'Изображение объекта', 'rw_' ),
						'id'               => "{$prefix}sector-object-image",
						'type'             => 'image_advanced',
						'max_file_uploads' => 10,
						),
	            
				
	            
            ),
        ),

And I call it in frontend

<?php $sectors = rwmb_meta( 'rw_sector' );
if ( ! empty( $sectors ) ) {
foreach ( $sectors as $sector )
{
    echo '<div class="object-block">
    
    		<div class="object">
    		
    			<div class="sector-object-text">';
    		
				$title = isset( $sector['rw_sector-title'] ) ? $sector['rw_sector-title'] : '';
		
				echo '<h3>' . $title . '</h3>';
    			
				$description = isset( $sector['rw_sector-description'] ) ? $sector['rw_sector-description'] : '';
		
				echo '<p>' .$description.'</p>';
				
					
				echo 
				'</div>';
    		
    		
				$object_img = isset( $sector['rw_sector-object-image'] ) ? $sector['rw_sector-object-image'] : '';
				if ( $object_img ) {
				
				echo 
				
				'<div class="sector-object-img">
						
					<div class="slider slider-for">
    		
							<img src="' . wp_get_attachment_image_url( $object_img, 'type=image_advanced&size=full&multiple=true' ) . '">
    		
					</div>
				</div>';
				}
    		
    		
    		
    echo	
    		
    		'</div>
		
		</div>';
	} 
} ?>

Title and description are displayed, but no images.
I even tried with 'max_file_uploads' => 1, but no luck

Thank you, Anh Tran. That works.
Good product, good support.

<?php $group_value = rwmb_meta( ‘rw_mygroup’ );

foreach ( $group_value as $group_value )
{
echo ‘<div>
<div class=”image”><img src="' . $group_value['rw_img'] . '"></div>
<div>’ . $group_value[‘rw_textfield1’] . ‘</div>
<div>’ . $group_value[‘rw_textfield2’] . ‘</div>
<div>’ . $group_value[‘rw_textfield3’] . ‘</div></div>’;
} ?>

Everything works great with file_input, but not retrieve img with image_advanced. Could you please provide the php code to call image_advanced attachment in the template.
