Interesting, your screen looks just like mine and does not indicate that the landing lights are on (but the landing light switch is on), on the upper middle display panel. I see it indicates the seat belts are on but I am used to seeing, on other Airbus aircraft, a line to the left of the "seat belts" indication an indication that the "landing lights" are on, if they are.
Also I don't know how to clear the WASM folder for this aircraft in MSFS 2020, is that applicable, I only fly MF2020, MS2024 is much too unstable for my taste. Thank you for looking into this and helping.
