Erases when you back up from iCloud

So I like the app except for the fact that between my two devices it wont accept backups from the other. So stuff ends up getting erased. Whole workouts gone. Saved workouts erased. It should be able to add on to the iCloud stored backups. Not erase when one device doesnt have what the other has. Additionally, tried to email support and there is not an option to do that! Good app. Bad performance.

And now it shuts down every time I post an exercise.
