In Pivot table, values are missing while dividing each cell value with totals

[divyajayan]

My requirement here is to divide each cell value with the totals. That means in Backlog target, it should give 707/871 which is 0.81. Similarly I need the values in rest of cell like 5/871, 12/871, 7/871, 23/871 goes on.. However I am getting values in certain cells only not all. Not sure what I am missing here. The formula I am using is (aggr(Count(UNIQUE_ID),MONTH_DUE,DELIVERED_BY)/aggr(Count(UNIQUE_ID),MONTH_DUE))

Can someone help me to figure out the issue?
