multiple rows with measures value

hi, I have a question using flexmonster!
I will use 4 rows and some of measures for chart.
when I make a table, flexmonster give me value that I don't need.
I attached a picture.
I don't need 3 yellow value, so I want they are marked with blank ( I just want red one )
Is there any way to resolve my problem?
this is parts of my js code.

rows: [
    {uniqueName: "date"},
    {uniqueName: "type"},
    {uniqueName: "action"},
    {uniqueName: "reason"}
],
measures: [
    {uniqueName: "total", grandTotalCaption: "total"},
    {uniqueName: "cnt10", grandTotalCaption: "10"},
    {uniqueName: "cnt20", grandTotalCaption: "20"},
    {uniqueName: "cnt30", grandTotalCaption: "30"}
]
