Lost data, fitness a complete mess

So I finally got myself motivated to start exercising again, and made a goal of starting to close my rings daily. I have worked hard now for 5 days in a row to do so. Then today it showed my Monday move back down to 694/700 calories. No clue why. A google search said to add in data manually from the health app. So I tried to add in a walk for Monday to put my ring back closed. Instead of that, it added 1 minute workouts for every minute of Monday-Wed (Today) which further trashed my goals. The only option was to edit and delete all of the entries, which removed everything for workouts for 3 days. This is extremely disheartening. Not sure why Apple has zero protections on this data, very clearly discounting the importance of it to many users. Is there any way to fix this, or is it another instance of Apple letting me down. (I still never got over itunes destroying my mp3 collection years ago).
