Stereo Assembly USB C light stays lit after ignition off.

Question, does anyone else noticed the light around the stereo USB-C plug stays lit after ignition off?

There are two USB-C plugs next to the cig lighter port behind the center cup holders. The far left plug directly to the radio display. I just noticed the light around this plug stays lit after ignition off. Faulty or normal? Only the middle USB-C light turns off on ignition off.

Tried uploading a photo but keeps failing.
