Tesla integration: charging rate sensor charging_phases wrong

Hi,
Is it only at me that the sensor.car_charging_rate_sensor shows a false charing_phase value? For me it shows only 2 phases if i charge with 11 kw. The App shows all 3 (of couse) and the car is definitly pulling 11kw power. I see that over multiple version. Maybe its an issue with the API of Tesla?
Thanks.
