Group field disappearing after updating post

I created a group field.
And I can add multiple fields.
After I press update to update the post all my fields disappear except for one.
Can you please check in my code to see what the issue might be.

<pre><code><?php
/**
 * Registers the splash pricing plan post type.
 *
 */
function splash_location_custom_post_type() {
  register_post_type('splash_location',
    array(
      'labels'      => array(
        'name'          => __('Locations', 'textdomain'),
        'singular_name' => __('Location', 'textdomain'),
      ),
      'supports' => array( 'title', 'custom-fields' ),
      'menu_icon'   => 'dashicons-admin-page',
      'public'      => true,
      'has_archive' => true,
      'show_in_rest' => true,
     )
  );
}
add_action('init', 'splash_location_custom_post_type');

add_filter( 'rwmb_meta_boxes', 'splash_register_location_info_meta_boxes' );
function splash_register_location_info_meta_boxes( $meta_boxes ) {
  $meta_boxes[] = [
    'title'      => 'Main info',
    'post_types' => 'splash_location',

    'fields' => [
      [
        'name'  => 'Location title',
        'id'    => 'splash_location_title',
        'type'  => 'text',
      ],
      [
        'name'  => 'Location description',
        'id'    => 'splash_location_description',
        'type'  => 'textarea',
      ],      
      // More fields.
    ]
  ];

  $meta_boxes[] = [
    'title'      => 'Hours',
    'post_types' => 'splash_location',

    'fields' => [
      [
        'name'  => 'Schedule',
        'id'    => 'splash_location_schedule',
        'clone' => 'true',
        'add_button' => '+ Add a schedule',
        'type'  => 'group',
        'fields' => [
		      [
		        'name'  => 'Location schedule details',
		        'id'    => 'details',
		        'type'  => 'text',
		      ],
		    ],
      ],
    ]
  ];

  return $meta_boxes;
}
