2016 Kia Sedona LX open door indicator light

Hello, my recently purchased Sedona has automatic sliding doors. My door indicator light comes on and off while driving, along with internal lighting. So far, it seems to stay on when stopping at a stoplight or when parking. I’m pretty sure it’s a problem related to the driver side. If at a stoplight I’ve had success in opening and closing the driver door. However, when parked and shut off engine the light stays on until I open and close the driver side sliding door. I’m afraid to take it to a mechanic or dealership because of how much they’re likely to charge. Ideas on what’s going on, what to do, or other help much appreciated… Daniel Dickens, TX
