Sorting group field elements gets the fields values messed up

Hi!

I have had this weird problem recently.
I have got a group field defined. Something like that:

$service_products_repeatable = $service_metaboxes->add_field( [
		'id'      => $pref . 'services_products',
		'type'    => 'group',
		'name'    => 'Products list',
		'options' => [
			'add_button'    => 'Add product',
			'remove_button' => 'Remove product',
			'sortable'      => true,
		],
	] );

	$service_metaboxes->add_group_field( $service_products_repeatable, [
		'id'   => 'product_name',
		'name' => 'Product name',
		'type' => 'text',
	] );

	$service_metaboxes->add_group_field( $service_products_repeatable, [
		'id'      => 'product_description',
		'name'    => 'Product description',
		'type'    => 'wysiwyg',
		'options' => [
			'media_buttons' => false,
			'textarea_rows' => 10,
			'teeny'         => true,
		],
	] );

The problem is that when I change the fields order in the wp-admin UI, the values of the wysiwyg fields gets mixed up. They get mixed up during sorting, I do not have to update the post for the effect to take place.
By “mixing up” I mean that some values from one field get assigned to another, sometimes the values disappear etc. When that happens, the affected wysiwyg fields gets broken – it looses its UI (text formatting buttons etc) and becomes unresponsive.
Has anyone ever experienced this weird behaviour? Is it a known bug?
I am using the latest version of CMB2 and WordPress.

Thanks in advance for any help ??
