Conditionally Filter Specific Visuals Based on Current User Logged In

You can't use VALUES on its own, as the CSR table is being filtered by having the CSR name in the slicer or table visual. I think the below works, using REMOVEFILTERS

02 Should Current User Be Filtered = 
VAR CSRFilterEmailList = 
    //ONLY NON-MANAGER CSR'S SHOULD HAVE DATA FILTERED
    CALCULATETABLE(
        VALUES('Dim CSR'[Email]),
        'Dim CSR'[IsManager] = 0,
        REMOVEFILTERS( 'Dim CSR'[Name] )
    )
VAR CurrentUser = [01 Current User]
VAR ShouldCurrentUserBeFiltered =
    //VERIFY IF CURRENT USER LOGGED IN IS A NON-MANAGING CSR.
        //IF YES THEN WE NEED TO FILTER CSR SLICER & CSR TABLE VISUALS BY CURRENT USER LOGGED IN
        //IF NO THEN DO NOTHING.  I.E. DO NOT FILTER THESE VISUALS BY THE CURRENT USER LOGGED IN
    IF(
        CONTAINS(CSRFilterEmailList, 'Dim CSR'[Email], CurrentUser),
        1,
        0
    )
RETURN ShouldCurrentUserBeFiltered
