Empty Weight on Resync

Has anyone noticed when resyncing an aircraft, the weight and balance seems to be resetting.

No matter what I set as my empty weight CG (in the aircraft editor), the ‘current CG pos Z’ always resets to the same figure once the model reloads.

Between the resync beginning, and before the model loads, it shows the correct CG. Once the model appears it changes again to another arbitrary figure, making my tailwheel aircraft slam its nose into the ground.
Manually editing the .cfg and restarting the sim doesn’t seem to help either, once the aircraft is ‘resynced’.

Anyone else noticed this?
