    The filter you're placing on Answer[Key] = 6 does not propagate to the Customers table. Therefore the only filter  propagating to the customer table is the answer table as it is (without Key = 6 ). 

    CALCULATETABLE will create a table filtered by Key = 6 which is then passed to CALCULATE as a filtered argument

     

    The expanded version of Customers does not contain coulmns from the Answer table, unless bi-directional filter is activated, which i dont recommend
