New Charts app in SC8 field labels don't work

I designed an chart type app in SC8 and in the fields section you can give the field the title. When the app is run the chart legend shows the db field names and not the title I defined in the field. I can’t find any settings to change for it to use the title. I tried giving the fields an alias but they don’t show up to sum and aren’t available for the graph. I really can’t change the actual field names in the DB. Now users will be asking what these mean since the field names aren’t descriptive enough. Is this a bug? Why would there be a place for a field title when it doesn’t even show up?
