Combo Chart : Drill down and show as table : not showing the %GM correctly

[KRISH80]

Dear Experts,

I am using a combo chart ( Colum + Line) to show the country wise sales and GM%. I have added Accouts as drill down and when i try to click on the 'Show as table' by clicking on 'drill down' button, the % GM is not showing appropriately. Any idea what could be the issue here ? Kindly refer to the pictures below... look at the GM% in the table
