Problem with ALL/ALLSELECTED while creating a heatmap

Hey there.

Here's the file link used for this example: heatmap.pbix

I'm currently working on the creation of a heatmap by using a matrix. In order to do so, I'm trying to retrieve the moment with the highest income in a given week, but I need to consider both the week day (like Monday, Dec 9th; Tuesday, Dec 10th...) as well as the contact hour (in the column headers). 

With the following measure I've authored, it worked for both the week and the week day lines where the moment took place (in blue frame, in the second matrix), however I still need that the cells inside the orange frame display the number 79 (income of the busiest moment of the week, as highlighted in the green cell of the first matrix). 

heatmap = 
VAR _min_year = CALCULATE ( MIN ( f_tickets[date_start] ), REMOVEFILTERS () )
VAR _max_year = CALCULATE ( MAX ( f_tickets[date_start] ), REMOVEFILTERS () )
VAR _result =
    MAXX (
        CALCULATETABLE (
            CROSSJOIN (
                DISTINCT ( d_calendar[week_en_us] ),
                DISTINCT ( d_calendar[day_name_en_us_with_day_name] ),
                DISTINCT ( d_hours )
            ),
            d_calendar[year] >= YEAR ( _min_year ),
            d_calendar[year] <= YEAR ( _max_year ),
            ALLSELECTED ()
        ),
        [count_tickets] 
    )
RETURN
    _result

The desired outcome would be that all the numbers in the week shows the same number as the busiest moment, so in the example I provided all the cells shoud be showing 79 for the W50, Dec 9th, 24, not only the Monday, Dec 9th row (and the week header). For the Week 49 (W49 Dec 2nd, 24), all cells shoud be showing the the number 91. For the Week 48, 1693 and so on. 

Thanks in advance (=
