I set the Current Limit (amps) in Charge Options to 24 amp for a 30 amp circuit. I came back later and the line is now shaded and shows 6 amps. I rebooted the system by holding the center button down for 20 seconds. I also turned the car off through the menu. The car charged at 24 amp limit but this option remains shaded at 6 amps. I cannot change the setting. Has anyone seen this? Anyone solved this?
