The ECAM: "FUEL IMBALANCE CORRECTED" uses the same trigger as the ECAM: "FUEL WINGS NOT BALANCED".
The FUEL WINGS NOT BALANCED triggers at an imbalance of 3.000 kg between wing tanks. When, in real life, you balance the fuel and the situation is corrected you get the ECAM: FUEL IMBALANCE CORRECTED.
The inibuilds A350 uses the same trigger (i.e. 3.000 kg) for this, which is incorrect. The FCOM doesn't actually state when this happens, but it will be a lot closer to 0 kg imbalance.
Just a minor issue
