Activtion groups not working with Rocket Engines

Yesterday I reported a bug stating that Activation Group stopped working on Rocket engines with realase date 3/27. I thought that it was only effecting Craft built with earlier models but i was wrong. In the attached picture The center cluster of Ions is the Main Drive, the outter 6 are Lunar Drive. Both at launch were deactivated and as expectet throttle didnt fire them. Then I used the activation groups to get them going and that worked fine. BUT, with this new ship, built yesterday 3/30 once activated the groups wont disable. This craft also has an electric motor that rotates the purple ring around the main engines, its assigned to the same acivation group as the main engines and works fine for turning the electric motor on and off. There is also landing struts assigned to another Activation group and thats works fine as well. It only affecting motors. hank You, Ron
