Slicer not filtering Cumulative Total

Hi, 

I have a dataset that looks like this:

I have a measure that returns the sum of amount that's been awarded:

FY21_Awarded = CALCULATE(
    sum(FY21[Amount]), FILTER(FY21, FY21[Stage] = "Awarded"))

I have another measure that returns the cumulative total of the amount awarded:

FY21_Cumulative Total = CALCULATE(
    FY21[FY21_Awarded], 
    FILTER(ALL(FY21), FY21[Donor Decision Date] <= MAX(FY21[Donor Decision Date])))

This all works great as anticipated:

 However, as soon I user the source slicer I get the following:

You'll see that the total returns $34k for the one record. However, the cumulative total is returning $1.42M. I understand that this is working as the measure intended and that on the date of the slicer selection of "Field" the cumulative total including the $34k is equal to $1.42M.

However, I would like the slicer to filter the cumulative total measure:

• If nothing is selected it would return the cumulative total for field and HQ. 
• If field or HQ is selected it would only return the cumulative total of awarded for either Field or HQ. 

I'm essentially looking for a dynamic cumulative measure based on the field and HQ slicer. 

Any information on how to proceed would be greatly appreciated.

thanks in advance!
