We have the storage, which are ment

We have the storage, which are mentioned on the below per MAWB, transport kept the cargo more than one week because awb corrections, this is the cost from transport and is net to us.

Can you please explain 50/50 please? does it came from AF, SSC? or how it should be? I prefer to be clear on this so I can send you on the next shipments by myself without asking your confirmation and taking more time to send you our invoice.
