Mostly works but some values fail on sync

The sync works for core values like active energy, steps, and distance. It throws an error on steps climbed and claims to sync sleep but there are no data transferred. I assume these are because my Zip doesnt support them and the Fitbit UI doesnt support entry of these. So why does this app keep telling me the sync was successful?

It claims to sync weight but again, no actual data are transferred. This is disappointing. It would be nice if the sync supported water consumed so that I could see all of my FB data - including those from other apps - in one place, which is really the point of Data Manager.

All of this would be fine in a free app but for $2.49, I expect better.
