Card Value not changing based on slicer selection

Hoping amitchandak may be able to help!

I have a card that should reflect a unique count of users in table Facts1.  I have a bridgetable 'Region' with 1 to many to Facts1 and Facts 2.  Facts2 relates to Facts 1 with 1 to Many Unique ID.

Requirement - Region Slicer should change the user count from Facts1 based on region selected.

I have set up a measure to collect slicer value as well as another to attribute '1' to region selected in Facts 1 and used as visual filter

In table view this works perfectly, so I know formulas/measures are right.  However when I switch to card view, the number displayed does not change at all? 

What am I missing?

Measure 1:  

SlcRegion = SELECTEDVALUE('Region Main'[Region])

 

Measure 2:

SelRegion =

var _sel = [SlcRegion]

var _Reg = MAX('New Dashboard'[Region])

Return

If(CONTAINSSTRING(_Reg,_sel),1,0)
