CONF iture
Those figures were the original ones given to the crew on the flight plan. They are used for initial input into the MCDU and are then updated when the flight closes and a final ZFW is given. The fuel requirements are then finalised, inserted in the MCDU & then the performance figures are computed. Any significant change after that should be advised to the crew who would then get new performance figures. You would also check the loadsheet to confirm the ZFW, T/O wt & Ldg wt.
I don't know the cargo set up to catch errors but as I said before, until details emerge, all bets are open: human and/or technical.
To err is human, to really
it up just add a computer/stress/more humans/time change/management etc etc
