Reverse Running Total with Blank Columns

Got a weird one for you guys. I am building a reverse running total matrix that has the week in the quarter across the columns. The rows show the different year/quarter combinations. The measure is meant to reflect the revenue that was generated on or after the current week based on the column. So, for example, there was a total of $2,486,602 in revenue for 2019 Q1, as shown in the table below. In week 1, the entire revenue for the quarter is shown, because all revenue was generated on or after week 1 in the quarter. This amount should logically decrease for each week throughout the quarter. If no revenue was generated in a specific week, that column should reflect the same amount as the column before it...

That's where I'm running into an issue. When a given week does NOT have any revenue data, the matrix cell is NOT showing the same value as the prior column. Instead, it is showing the the full revenue for the quarter (equal to the value in the week 1 column).

See the yellow highlighted cells below for an example. For 2019 Q1, week 13 reflects the same value as week 1. I have no idea why the same didn't happen for 2019 Q4...

Here is another example, this time with 2019 Q1 split by region. You can see that the same thing is happening for any week where there is no revenue data for the week/year/quarter/region combination.

I need those yellow cells to be equal to the prior column. Here's what I've already tried:

• I've tried adding "+ 0" to the end of the measure. Doesn't work.
• I've tested adding $0 lines to the data table this pulls from. That does work, however it is not an ideal solution for a host of reasons. I don't want dummy data in the model if I can help it.

I'm fairly certain this should be doable by adjusting the measure formula, but all of the forum posts I've seen regarding this topic discuss how to fix the blank column issues for running totals and not for reverse running totals.

Thanks so much for your help! Here is my measure formula for your reference:

Revenue On or After =

CALCULATE(

    SUM('Revenue Detail Table'[Revenue]),

    FILTER(

        ALLSELECTED('Revenue Detail Table'[Week]),

        'Revenue Detail Table'[Week] >= MIN('Revenue Detail Table'[Week])

    )

)
