split order Bad delivery cost calculation on splitted order (PS 1.7.7.4)

[MaX3315_2]

Hi, 

When i validate my cart with two products :
- Product A, 12Kg, using a free carrier A 
- Product B, 10Kg, using a second carrier B (with cost by weight configured)

I obtain two orders :
- Order A with free shipping cost (OK)
- Order B with cost using 22Kg grid slice... and not 10Kg.   (in BO order view and carrier tabs Prestashop display the good carrier B and the good weight 10Kg... but the bad cost...)

If i try an order with only one product B, i get the good shippging cost slice.


Any idea?
