Problem in Waterfall Chart values ordering in SAP Design Studio

Hello Members,

I am facing a problem in Design Studio working with Waterfall Chart.The Chart seems to increase upwards (when it should be step down as per the requirement) with values in random order.Moreover the series takes its name from the first Key figure selected(in my case Gross Price/Ton). See the picture below.When I mouse over on Other Expenses Per ton,it shows label of Gross Price/Ton when on Other Expenses/Ton. Where am I going wrong?

Please throw some light on the same.

Regards
