I used to have one of those. You might try pushing the test button after it has moved forward and observing how it acts. I think you will find that the "box" will be pushed back to the seat as the actuator arm extends. Maybe you need to move the seat farther forward, but seeing it in operation will help you determine that.
I've operated it using the test button 10's of times and cannot figure out how to stop it from jumping out of position. And I have tried pushing the seat very close to it too. Which causes the brakes to be applied. When I just back it off from that, after 3 operations, it's again jumped out of position.
