CWB: Amount not rounded when uploaded from spreadsheet

In CWB Allocate Merit and Lump Sum page, the Target Amount field has been defined to rounding code of 'Round to Nearest One'. All amount with decimal value entered on the worksheet are rounded to the nearest one.

However, when downloaded to spreadsheet, Target Amount field can be entered with decimal value. And when uploaded, the decimal value is captured on the worksheet. Amount was not rounded. Only when change is triggered on the amount, the rounding works.

Please help.

Thanks.
