This doesn't sound like a software related issue. I recommend contacting the manufacturer of JD, which is EZ-Robot. Here's a direct link to their contact support page: https://www.ez-robot.com/Support/

Probably an issue with the little potentiometer inside the servo or it's control board. A new servo will probably fix this. Follow DJ's link and get help from the ones who stand behind your servo. Hopefully they will send you a new one.
