New Customer Calculation

Hi All, I'm probably doing something dumb, but I cannot figure out how to make this formula work properly. This is supposed to ignore any slicer/filter on the ProfitCenterGroup Table, but when I click the slicer, it doesn't seem to ignore it. In addition, it calculates way too low, even if it were considering the filter setting. Perhaps this is something in the relationships?? 

Absolute New Customers =
COUNTROWS (
FILTER (
ADDCOLUMNS (
VALUES ( PLS_Analytics[End_Customer_Key] ),
"PreviousSales",
CALCULATE (
COUNTROWS ( PLS_Analytics ),
ALL ( 'ProfitCenterGroup Table' ),
FILTER (
ALL ( 'RA_Daily_Calendar' ),
'RA_Daily_Calendar'[Date] < MIN ( 'RA_Daily_Calendar'[Date] )
)
)
),
ISBLANK ( [PreviousSales] )
)
)

Here's an image of the relevant tables and relationships.

Help is appreciated. Thanks in advance!
