End wrist servo doesn't detach like other motors

Firmware Version: 4.3.2

Operation System: Win 10

uArm Controlling Method: Python
{‘device_type’: ‘SwiftPro’, ‘hardware_version’: ‘3.3.1’, ‘firmware_version’: ‘4.3.2’, ‘api_version’: ‘4.0.3’, ‘device_unique’: ‘’}

The end effector wrist servo, which I assume to be the 3: HAND value from the set_servo_detach/attach documentation does not behave as expected.

I want to be able to position the arm manually to the greatest extent. If a device is attached to the pump I am unable to rotate it to the appropriate position manually without being able to rotate the servo by hand.

Hi, the forth servo(motor_id=3) could not be disattached, no matter firmware 3.2.0 or 4.x.x. Thanks
