Ebike Smart range annoyance when not paired to ebike

I ride an eMTB with a Bosch CX4 motor.  It's has no connection to my Garmin 1040 but every time I ride with a planned course it tells me "this ride will exceed ebike range". My 1040 has the latest software (with the course indicator I can actually see [finally]).  Can anyone tell me how to turn this crazy message off. How can it be giving me this useless message when there is no ebike paired?
