Error using measure with scorecard

Hello all,

I am using a mesaure with the DAX formula- CALCULATE(COUNTA(Table 1[SalesNo]),DATESMTD(Date Table[Date1])) for Mesaure A and CALCULATE(COUNTA(Table 1[SalesNo]),DATESMTD(Date Table[Date2])) for Measure B. Both these mesaures are being used in a card visualization and hence I dont have any date slicers. Mesaure A is displaying accurate results even without date slicer. But Mesaure B will show Blank if no date slicer is used. I cant have a date slicer there as per requirements. What should I do?

Thanks in advance.
