Narazil som na tento problem. Dopatral som sa k tomuto commitu https://github.com/woocommerce/woocommerce/commit/1fa36b5f1517333aa01ca0bcbfdd06211b4a4eb7#diff-e0bc260f1e60bc4be6a6956affee2637 a problem je spomenuty aj na konci v readme.txt tohto pluginu https://plugins.trac.wordpress.org/browser/wc-nastavenia-skcz/trunk/readme.txt .

Fixol som to bez potreby dalsej upravy tohto pluginu alebo woocommerce s tymto kodom v separatnom plugine.

function aa_woo_hotfix_nastavenia_skcz($fields) {
	global $post;
	if ( ! isset( $fields['company'] ) || ! is_array( $fields['company'] ) ) {
		return $fields;
	}

	$field_keys = [
		'wc_nastavenia_skcz_billing_as_company',
		'wc_nastavenia_skcz_billing_company_vat_id',
		'wc_nastavenia_skcz_billing_company_id',
		'wc_nastavenia_skcz_billing_company_tax_id'
	];

	$order_id = $post->ID;

	if ($order_id > 0) {
		foreach ($field_keys as $field_key) {
			if ($fields[$field_key] && !$fields[$field_key]['value']) {
				$fields[$field_key]['value'] = get_post_meta( $order_id, '_'.$field_key, true );
			}
		}		
	}

	return $fields;
}
