Measure issue

Hi, I have a transaction table that has Region (Ex: APAC), Country (Ex: India), and a IS_IN_SLA (Yes or No), BU, and a bunch of other columns like submission date, etc. There is a slicer on the country, date, etc

Now, I want to create a visual table which shows me the following - BU, In SLA - Region, In SLA - country.

So for example, let's say the slicer for date is filtered from 1/1/2020 to 1/12/2020. Within that filter, it should check the country selected in the country slicer, say India and calculate the In SLA country. Now from the same table it should gather that India is in APAC and calculate the In SLA - region for entire APAC. In SLA is just wherever the IS_IN_SLA is Yes

Dax_IN_SLA_Country =

CALCULATE(

    COUNTROWS('TRANSACTION'),

    'TRANSACTION'[IS_IN_SLA] = "Yes"

)

Dax_IN_SLA_Region =

VAR SelectedRegion =

    CALCULATE(

        MAX('TRANSACTION'[REGION])

    )

RETURN

CALCULATE(

    COUNTROWS('TRANSACTION'),

    'TRANSACTION'[IS_IN_SLA] = "Yes",

    'TRANSACTION'[REGION] = SelectedRegion,

    REMOVEFILTERS('TRANSACTION'[CLUSTER_NEW])

)

I'm facing this issue when I built it out. The country measure is simple because it respects all filters. The region measure is changing even when i select countries in the same region. FYI - There is no way to select multiple countries
