How to get the trailing 4 weeks of this

[novieee]

I tried the solution from other threads in forum but it cant seem to work with mine. I want to get the trailing 4 weeks of my Actual, this actual is in MEASURE, here is the formula for that 

Actual =

IF(

    SELECTEDVALUE(CalendarTable[YearNum]) >= 2016 && SELECTEDVALUE(CalendarTable[YearNum]) <= 2021,

    DIVIDE(

        [sumLossStandardChangeToolFreq],

        (DIVIDE([SumAvailableTime], (8 * 60)) / 10)

    ),

    DIVIDE([sumLossStandardChangeToolFreq],[sumNumberOfShift]) * 10

)

 I thought I solved this one, but when I checked it again it isnt showing any output here is the formula of my trailing 4 weeks average 

Trailing 4 Weeks =

VAR MaxDate = MAX('CalendarTable'[Date])

RETURN

    AVERAGEX(

        FILTER(

            ALL('CalendarTable'),

            'CalendarTable'[Date] >= MaxDate - 27 && 'CalendarTable'[Date] <= MaxDate

        ),

        [Actual]

    )

The 2016 - 2021 is summarize month thats why its like that 

And I dont want it to be included in getting the Trailing 4 weeks averages

I hope someone can help me. Thank you!
