Order weight does not calculate the weight

Hi,
you remember as we spoke about the Order_Weight tag here:
https://support.balbooa.com/forum/gridbox/18650-order-weight-on-invoice-email#88656
Than you implemented it fantastic, but now I got an order with 3x 1product and the order weight tag shows the weight only for one product. I dont think it is what the tag should do :)
