Restow in BAPLIE file

Some days ago I received the following complaint from an EDI customer:

"However everytime we receive a departure BAPLIE from your Terminal, where we have performed restows, we always get the restowed units showing as loaded from your port which clashes with the restowed unit."

In the beginning, I thought to have messed up some mapping rules but after having a look at the config file I realised that, at my end, everything was set-up properly. 

Here is the EQD segment group concerning a unit restowed by my Terminal:

(...)

LOC+147+0250208::5'
MEA+WT++KGM:6960'
LOC+9+ITSAL'  >> Place/port of loading
LOC+11+PTLEI' >> Place/port of discharge
LOC+83+PTLEI' >> Place of delivery (by on carriage)
LOC+76+ILHFA' >> Original port of loading
RFF+BM:1'

EQD+CN+ABCD1234567+22G1+++5'
(...)

I guess that customer's EDI translator has some issues in handling OPOL (Original Port of Loading) in conjunction with POL (Port of Loading): of course that's not up to me and, at least once, I was happy to close the support request without changing anything !
