. This is what I have recently figured out.
The servos are naturally positioned and I believe they do automatically set to the 0 position when you start them. But inside the FTC template, there is a new section for initialize position. Inside that section try posting this code.
servo[servoA] = ServoValue[ServoA];
this should keep servoA exactly where it is. (Check my syntax, I don't think that's exactly it.)
