DAX measures not filtering as expected

OK DAX gurus, I am having an issue with a technique I was trying to use to display currency symbols based on slicer selected. Here is my current setup:

I have 3 slicer that show our CONTINENT, MARKET, and COUNTRY. I have uploaded the sample data for testing. What I am attempting to do is show the symbol based on the slicer selection. First, I created measures for each slicer to display the symbol based on the selection in the slicer. Here is the DAX for that:

country_m = IF(HASONEVALUE ( 'DimLocation'[Country] ), VALUES ( 'DimLocation'[Country Symbol] ), "-")

continent_m = IF(HASONEVALUE ( 'DimLocation'[Continent] ), VALUES ( 'DimLocation'[Continent Symbol] ), "-")

market_m = IF(HASONEVALUE ( 'DimLocation'[Market] ), VALUES ( 'DimLocation'[Market Symbol] ),"-")

Then, I created a measure to display on a card visual, which my goal was to show the symbol based on the slicer selection as stated above. 

Label = 
IF (
    ISFILTERED ( 'DimLocation'[Continent] ),
    [continent_m],
    IF (
        ISFILTERED ( 'DimLocation'[Market] ),
        [market_m],
        IF ( ISFILTERED ( 'DimLocation'[Country] ), [country_m], " " )
    )
)

This does not work as intended. As you can see from the below screenshot, you should be seeing the symbol at the country level, but it is showing the market or continent level.
