I'm seeing the same in FS2020 with the AUTO default panel state enabled. The EXT1 & EXT2 don't light up. I've reinstalled the aircraft to and cleared the WASM directories. This happens when spawning at the gate. When I spawn at the runway the screen does turn on but seems to be in the startup mode and shows OIS not available and needs to boot up despite the other screens all fully functional. Changing the default panel state to ON GPU seems to get it working when spawning at the gate.
