during my flight I always get the amber fuel imbalance warning,when checking the tanks the left inner tank drops immensly and the right fills up,they're equal on take off but something weird happens when flying,the f;used 1+2 is nice and balanced but for some reason the left tank transfers its fuel to the right tank,anyone an idea what this causes?
EDIT: also just noticed it says FOB 14.000kg despite the left tank having around 2000 and the right 7500
