Chart - Data Label Format Refuses to Change

Attached image. Fourth bar from the right. Top orange rectangle.

You'll notice that I have the labels on this orange series formatted as "series name". 3 of the 4 bars are properly formatted and display the series name. The one incorrect bar (fourth from the right, top) refuses to display the series name and instead displays the value "1". The value box is clearly not selected for this series. Why is there this one exception. I want the series name "NC" to show on this bar, just like the others.

I've tried changing the one data point and then changing it back (to refresh the data) but it didn't help.

[PS - DONT LOOK AT THE IMAGES BELOW THIS LINE, I CANT FIGURE OUT HOW TO DELETE THEM]
