What happens when the profile is loaded is that the prefix and suffix commands you have are joined together to make full (composite) commands that VoiceAttack is listening out for. That means you have to say the complete commands all at once, without pause. From the log, it looks like you're saying the portions of the commands separately. For instance, it looks like you're saying, 'chief', waiting, and then saying, 'turn off the ground power'. The pause after speaking is making VoiceAttack look for a command called, 'chief' (which is not recognized) and then a command called, 'turn off the ground power' (also not recognized).
What VoiceAttack is really listening for in that regard is a complete sentence of 'chief turn off the ground power' in order to execute the command (one fluid sentence, no pausing). Try that and let us know how it goes.
