What is odd about the W&B screen is that the slider is labeled “Empty”.
That is something that shouldn’t be adjustable and is determined by the manufacturer of the aircraft and is redetermined when non-standard equipment is installed in the aircraft (which potentially changes the weight and balance of the aircraft).
Theoretically, the CG should be set by how you load the aircraft. I’ve been on small aircraft where the flight crew have moved passengers to different seats and/or move baggage to different storage compartments.
The whole slider thing seems whacky in MSFS.
