Completed / Processing / Cancelled should be llcalized

In the following code in class WCMp_Transaction it can be seen that the order status is not localized:

$status = get_post_status($transaction_id);
        if($status == 'wcmp_completed'){
            $transaction_status = 'Completed';
        } else if($status == 'wcmp_processing'){
            $transaction_status = 'Processing';
        }else{
            $transaction_status = 'Cancelled';
        }

As a result, even with 100% translated strings in po/mo files, transaction status is shown in English.
