FILTER() in CALCULATE () with VALUES() breaks aggreagtion "scope"

[Anonymous]

Hello,

I have the following Measure: 

    SUMX (
        'DC Volume',
        DIVIDE (
            CALCULATE ([Delivery Line Count OSR], VALUES ('DC Volume'[FCRateKey])),
            CALCULATE (
                SUM ( Forecast_ProductivityRate[Productivity Rate] ),
                VALUES ( Forecast_ProductivityRate[FCRateKey] )
            )
        )
    )

This produces the output of 1646.829 (which is correct) when put in a card visual. To visualize the result:

If I add a FILTER() expression like this:

OSR_FC_Rate_Worked_Hours = 

    SUMX (
        'DC Volume',
        DIVIDE (
            CALCULATE ([Delivery Line Count OSR], VALUES ('DC Volume'[FCRateKey])),
            CALCULATE (
                SUM ( Forecast_ProductivityRate[Productivity Rate] ),
                VALUES ( Forecast_ProductivityRate[FCRateKey] ),
                FILTER (
                    Forecast_ProductivityRate,
                    Forecast_ProductivityRate[From Date] >= [Selected Date SOMONTH]
                        && Forecast_ProductivityRate[To Date] <= [Selected Date EOMONTH]
                        && Forecast_ProductivityRate[ActivityNM / LABROLEV4ID] = "802-91"
                )
            )
        )
    )

Then the aggregation specififed with VALUES() breaks. Instead of summing up all the results of each division, it uses the total:

How can I avoid this behaviour?

The two tables DC Volume and Forecast_ProductivityRate have a many to one relationship (multiple lines in DC Volume relate to one in Forecast) based on FCRateKey (this is also a unique key in Forecast_ProductivityRate).

What's the point of using VALUES in the CALCULATE?  Should not make any difference?
