Data label values shows twice

JothiG , Open and check in the label. Have you enabled additional label items like details. Just keep one under value

Hi JothiG 

This happens because it’s a combo chart (columns + line) showing the same values in both series.

If you’re using two different measures that just return the same value, simply turn off data labels for one series (either columns or line) in the Format pane.

If you use the same measure for columns and line:
 The fix is to create a second measure that references the first, e.g.

Sales_Duplicate = [Sales]

Use [Sales] for one series and Sales_Duplicate for the other. Now you can disable labels on one series only.
