I had similar happen to me but for the life of me I can’t remember what the lights were set to when I got out & locked the car but when I got back in, switched the lights to auto ( so you see Auto On on screen ) got back out, locked the car & lights turned off
If it’s still happening I’d suggest
Get back in car, pedal on brake so it goes into Ready mode
Switch the lights over to Auto, if it says Auto On, get out lock the car
If you hot the switch & it says Auto Off, switch it again until you see it say Auto On, get out & lock car
Hopefully this should do it, good luck
