PSS Concorde refuel problem

[tpnavas]

Hi
I´ve just tried to refuel my PSS Concorde several times, and it´s not possible, if I refuel with 85.000 kg, at first it loads the amount of fuel, but a few seconds later, the amount drop to 62.000 kg and it´s impossible to fly from EGLL to KJFK with it, well, I have tried with 95000kg, and then drop to 68000kg and then to 64000kg, I don´t understand why ?!?!?!
I see that there are some Concordes here, so I don´t know if they use the PSS or other, maybe is a bug from PSS or not, thanks for your answers
