sensor.charger_current_offered at 6 A

[T-Bienert]

The Setup:
Wallbox: abb terra ac w11-g5-rd-pc-0
Homeassiatant OS
ocpp verson: v0.10.15

Charging works fine in general, but the value for sensor.charger_current_offered is set to 6 A, so the box is only charging at 6 A.
I don’t understand why.

here is a short debug log.
what I noticed "ChargePointMaxProfile not accepted (Rejected); will continue"
