Dryer instrument lights stay on, even when unit is off

I have a Maytag MED6000XW1 dryer. Recently, the lights on the power button, dial, and start button started staying on all the time - even when the dryer is off. I’ve tried unplugging it for 10-15 mins and plugging it back in to reset, but the issue remains. It’s only a minor annoyance, but I’m wondering if it indicates some other problem. The manual has no mention of this in the troubleshooting section. Does anyone know why this might be occurring? TIA.
