Copilot and Barometric Pressure Setting

When operating with the Copilot the barometric pressure settings do not adjust to revised settings notified. I don’t know why, or how I can adjust them myself but the consequence is that the aircraft plows into the landing lights because the aircraft is too low instead of landing on the runway! The sim says press [9] to reset it but that doesn’t work or I don’t understand [9].

Press ‘B’ to set barometric pressure on your analog meter < sim uses only this setting , it will not check the barometric pressure you set in a G1000 …

pressing B will also change the baro setting on the G1000…
