When I choose "Show All Data" from an activity in Health (iOS 8.1), I see a long list of data points with associated source app icons; but this list almost always seems to be incomplete and not to correspond to the data displayed in the dashboard.
For example when I choose "Walking + Running Distance", I see a bunch of data from "Phone", but none from recent days (the most recent entry is over a week old; today is Oct 21)
despite recent walks being recorded correctly in the dashboard ("Today" is Oct 21),
and despite the fact that those walks are from a different source (which I can confirm by choosing "Share Data" in the activity and selecting the source).
Is "Show All Data" not working properly? Is there a setting I need to adjust to get it to actually show all data?
