Moto G5S Plus MAC Address Error

[BigBig5]

I have a Moto G5s Plus with Oreo. Lately I been getting a message randomly in a gray box at the bottom of the screen that says “Set correct MAC address”.

How do I fix this?

Is this only when the phone is connected to a wi-fi network?

It happens on both.

Does it happen in Safe Mode as well? https://support.motorola.com/in/en/documents/MS123090/
