It seems the Activity App only displays data gathered by the Apple Watch itself, and is NOT updated by Apple's Health App. This is frustrating because the Health App takes data from the AW, iPhones, and even 3rd party Apps (Runkeeper, Strava etc.) and 3rd party hardware (Garmin watches etc.) and combines it all and usually does a good job of NOT creating a doubling of records. (ie. Watch data during a given time will override less accurate iPhone movement data if both recorded, or a Garmin cycling computer workout will overwrite inaccurate calorie and movement data from the Watch etc.)
The problem here lies with "goal setting." Since the Activity app only shows Active Calories, Movement, Standing etc. gathered by the watch, if you should take it off for your bike ride with a Garmin computer, or a marathon with your Garmin Watch etc. even though Health App is well aware of your activity the AW Activity Monitor will show you did nothing. I really wish the Activity monitor showed (or at least had an option to show) my Activity based on the HEALTH app data which contains not only the Watch data but my whole fitness life, no matter the source.
