Shipping Charges Shows 0 (Zero) in order section after split the order

You mail me 2 links
There are two methods:

1) Here is first one

2) Colissimo Integration (This plugin is specifically available for France/Paris). I am not sure if you are in this location.

but this link couldn’t solve my problem. When I’m splitting an order from the admin panel, shipping charges don’t show up after the order is split.
