Yesterday I flew from LEBL to LIRN and while I was setting MCDU at the gate I noticed  a strange thing: I have generated the loadsheet in the fuel planner and made an instant load. 9.2 kg FOB. Then I set the Block fuel data by pressing the LSK and appears 2.4 instead of 9.2 (I checked on the ecam that FOB was 9.2) At that point I manually changed that 2.4 in 9.2 So I was wondering if this bug happened to me yesterday could cause your engine off during the flight but I don't think so, t
