Filter on Dynamic Rolling Average on Month Slicer

[selpaqm]

Hi All.

I have created below measure to reflects always 3 month figures when month slicer is used. 

3R =
CALCULATE(COUNT('Order'[Order/ not ordered]),DATESINPERIOD('Date'[Date],LASTDATE('Date'[Date]),-3,MONTH)))

However, when I try to add salesman figures with below formula, and click to month slicer it is directly show just choosen month figures not 3 months.

3R John =
CALCULATE(COUNT('Order'[Order/ notordered])
,DATESINPERIOD('Date'[Date],LASTDATE('Date'[Date]),-3,MONTH),FILTER('Order','Order'[Salesman]="John")))

below you may find a sample.

@selpaqm , What is the expected value? Both table seem to have  same values

@amitchandak when click any month "working" table values are change and correct and also matching with below one but "not working properly" table start to show just clicked months figures

@selpaqm , I have removed filter in these two formulae and move them in calculate and seem like they behave same now

3%R Martha = DIVIDE(
CALCULATE(SUM('Order'[Order/ not ordered]),DATESINPERIOD('Date'[Date],LASTDATE('Date'[Date]),-3,MONTH),'Order'[Salesman]="Martha"),
CALCULATE(COUNT('Order'[Order/ not ordered]),DATESINPERIOD('Date'[Date],LASTDATE('Date'[Date]),-3,MONTH),'Order'[Salesman]="Martha"))

3%R John = DIVIDE(
CALCULATE(SUM('Order'[Order/ not ordered]),DATESINPERIOD('Date'[Date],LASTDATE('Date'[Date]),-3,MONTH),'Order'[Salesman]="John"),
CALCULATE(COUNT('Order'[Order/ not ordered]),DATESINPERIOD('Date'[Date],LASTDATE('Date'[Date]),-3,MONTH),'Order'[Salesman]="John"))

Appreciate your Kudos.
