Im try see out in a table box. I Have used measure as sum(net sales) but all values are coming same but actual values are different when I'm try check values in test app it is showing correct but when I'm try to check in original app values are coming same.
It sounds like there is no link (key field) between the Dimension field in your chart and the "net sales" field. Take a look at your data model in the Data Model Viewer.
