My target watts does not seem correct as a % of FTP. How do I fix this?

For workouts sync’d from Today’s Plan or TrainingPeaks, your target is based on your FTP on your profile in either Today’s Plan or TrainingPeaks.  For workouts provided by Wahoo, your target is based on your FTP within your Wahoo Profile.  To check this open the companion app; go to Profile; and scroll down to Power to set your FTP.
