Weird continual increasing degree

Today I just manage to run the robot arm, after I calibrate @ Rest position, I tried jogging but notice weird scenario.

1. I jog J1 for +/-10 degree, the J1 move none stop to left/right (depends on i press + or -), I need emergency stop it

2. I jog J2 -10 degree, it moved as expected, I jog +10 degree it no moving. Same with J3

3. There is others issue but I think come from same root cause.

Then I notice at Main Control J1-J6 all the degree keep increment eventhough the robot is not moving and I no perform any action. I think this is the main reason cause the error. Anybody have this experience and have clues for me?

Thanks in advance,

Edit: I'm added video to further explain:

1. I press emergency stop button

2. calibrate rest position

3. the angle all remain the same (as expected)

4. released the emergency button (J1-J6 angle value start changing, but arm no movement)

5. press emergency stop button (it stop changing)

6. release emergency button (J1-J6 angle value changed, arm still no move)
