VelocityOne not working correctly after update

Hi friends. I have updated my VelocityOne to 1.4. I know, beginner question, but it seems the default setting is not working anymore. Example, the throttle (black lever) is not working. Each time I pull it out, it went back. What happened, what should I do. It was fine before update. Sorry for beginner question, but it is frustrating. Thank you for all suggestions and advice
