If that is the case then there is likely only one version of the code (eases management of it), but a flag set Yes or No if the fee has been paid or not.
If so, and the right code to avoid the issue was actually installed in the aircraft but deliberately switched off, lawyers for the pax, especially those from the second accident, will have a field day.
