Context filter for measure

I created a Moving Average Measure like 

MA (7) = CALCULATE(sum(Item[Valor]);DATESINPERIOD('Calendar'[Date];LASTDATE('Calendar'[Date]);-7;DAY))/(CALCULATE(AVERAGE('Working_days'[DU_7])));

But it doesn´t correspond to my context filter. Whe I select some columns it still giving me the same results. I have two other columns I would like to slice (Product, Client).

How can I use context filter to my calculated field  (column or measure) ?
