Creating Matrix with a measure as row values with different years

[Tommy123]

So I have a mtrix I am creating bellow 

and this is fine and exactly how I want it where I have the Department and the current ear selected in my calanader slicer and the previous year.
My calander table is not connected to the main data, I am using dax to actually create the ThisYearSales measure where I then filter
Now there are a few things, when I switch the year in my calander table, I lose all my data except for like 3 departments, I checked for example the Department Audio and it has data for 2025 but once I change the year to 2025 it dissapears.
Next I want to the roll up on the department level to be the differene between the percentages if that is even possible?

The reason I disconnected the calander table is because It will only show the the year selected in my matrix when I want the selected year and the previous year

Need to see the definition of the measure

ThisYearSales =

VAR _thisyr = CONVERT(SELECTEDVALUE(PRC_00034_TEST[YEARNUM]),INTEGER)

VAR lastyr = CONVERT(SELECTEDVALUE(PRC_00034_TEST[YEARNUM]),INTEGER)-1

RETURN

IF(

        min(PRC_00034_RETENTIONBASE6[YEARNUM]) = (_thisyr)||

        min(PRC_00034_RETENTIONBASE6[YEARNUM]) = (lastyr)

        ,MIN(PRC_00034_RETENTIONBASE6[ACTFACTOR_SMRR])

)
