Excel Pivot Chart - Data lables question

All,

I’ve got a pivot chart in excel 2010. It is a bar chart with several groupings. If I drill down into any grouping, only 1 of the members of that subgroup will show data labels above each bar. This occurs regardless of how far down I drill. If I click on a series, it will actually highlight the exact space where the label SHOULD be in the label-less grouping, along with the same correctly-labeled spots in the other groups. It has nothing to do with font color, or anything like that, but i’m completely stuck. Does anyone have any ideas as to how I can force all labels to display at once?

Thanks!
