PHEV intermittent erroneous charging message

[BIC]

2022 GT PHEV with 28k miles. Charging always set to start at midnight due to lower electric rates. For the last few years, when shutting car down at home garage, dashboard said "charging begins at midnight." The last few months, it intermittently mixes the correct message with a message saying charging will start at xx : yy, with that being the current time. Regardless of the mystery message, the car correctly won't charge until midnight.

Any solutions to the messaging problem? Since the message only correctly works at home, I can see the dealer saying, "can't even attempt to duplicate." Thanks.
