Dynamic RANKS using CARDS elements

Hello Community, how are you? 

Could you please help me? PBIX file I am using.

Each Client participates in one or more than one GLOBAL GROUP. There are 02: HAVAS CREATIVE and HAVAS MEDIA. Under Global Group we can have Groups (BETC, HMG and HWW).

Desire outcome using cards: When I select a single Client, but do not select any Global Group nor Group, ranking will be considered as overall, comparing all Clients with each other. When I add a selection with Global Group ranking will drill down to this level and the same situation when I select Client + Global Group + Group.

Considering what I have in pbix file:

*** 1 Matrix results considering as example client "RB" (All correct):

• Overrall ranking = 2
• + Selecting Global Group as HAVAS CREATIVE = 1;
• + Selecting Group as HWW = 1;
• + Selecting Group as BETC = None (because RB does not belong to this Group).

 *** 2 Slicer results selecting client "TIM" and using both "Z_Rnk_Individual" and "Z_Rnk_Overall" measures (Wrong):

• Overrall ranking = 2 (correct should be 1 as Matrix);
• + Selecting Global Group as HAVAS MEDIA = 2 (correct should be 1 as Matrix);
• + Selecting Group as HMG = 2 (correct should be 1 as Matrix). 

Measures:

Z_Rnk_Individual =
IF (
    ISBLANK ( [Tot Bil Pilot BRL] );
    BLANK ();
    RANKX (
        ALL ( Pilot[CLIENT] );
        CALCULATE ( [Tot Bil Pilot BRL]; ALLSELECTED ( Pilot[CLIENT] ) );
        ;
        0;
        DENSE
    )
)

Z_Rnk_Overall =
IF (
    ISBLANK ( [Tot Bil Pilot BRL] );
    BLANK ();
    RANKX ( ALL ( Pilot[CLIENT] ); [Tot Bil Pilot BRL];; 0; DENSE )
)

Thank you so much in advance for your time and support. I hope you can help me to keep moving forward in this journey :)
