Sorting calculted measure with condition

Dear all

I have problem to sort value in chart (Top 10), with calculated measure 

Measure "MMonth-NPL>90" is calculated with condition to filter Year and Month Filter. 

Year and Month Filter is use for first chart (above) to show trend 4 month latest and second chart to show current (as year month Parameter)

MMonth-NPL>90:=var Ldate = EOMONTH(date(max(Year[Year]),max(Month[Month]),1),0) //Last date

var Fdate = date(max(Year[Year]),max(Month[Month]),1)
var Unit= FactNPL[M-NPL>90] //Calculation

return

if(MIN(DimTime[Date])<fdate,
blank(),
if(MAX(DimTime[Date])>Ldate,
blank(),
Unit))

And  Measure "[M-NPL>90]"  also calculated measure to filter amount of [M-NPL>90] is Unit or Amount from fact table

M-NPL>90:= var Unit =1 var Amount =2  Return IF (MIN(DimMeasure[MeasureID])=Unit,sum(FactNPL[NPL>90Unit]),sum(FactNPL[NPL>90Amount]))

The sorting function in chart is not working for measure selected (Chart 2)

Thanks
