The commands your keys are configured to execute functions in the third-party VAICOM plugin; have you contacted the author of said plugin (as well as the profile) about this?
VoiceAttack by default listens unless told otherwise. This is not an explicit "mode", and would not invert if no changes are made to the settings.
If you create a command to disable listening, and another command to enable listening, containing only the "Make VoiceAttack Stop Listening" and "Make VoiceAttack Start Listening" action, respectively, does the same issue occur?
