Create a measure like the following and use it in your matrix instead:

Your Measure = 
DIVIDE(
    SUM(YourTable[YourColumn]),
    CALCULATE(
        SUM(YourTable[YourColumn]),
        ALLSELECTED(Yourtable[YourMonthColumn])
    )
)

Give it a thumbs up and accept as solution if you find this helpful!
