Date Parameter Based on Fields Not Working with USERELATIONSHIP

I am at a dead-end trying to figure out why my date table, on it's own, works just fine with all my measures, but will not work with my Parameter ( New parameters > fields > then the date fields I custom created are chosen)
Meausre Example:

Open Order = 
    CALCULATE(
        SUM('Order Summary'[Open Order Ind]),
        USERELATIONSHIP(Dates[Date],'Order Index'[Referral Date])
    )

Calculated Column Example:

Yesterday = IF(Dates[Date] = (TODAY()-1),Dates[Date])

Parameter:

Date Filter = {
    ("Today", NAMEOF('Dates'[Today]), 0),
    ("This Week", NAMEOF('Dates'[CurrentWeek]), 1),
    ("This Month", NAMEOF('Dates'[CurrentMonth]), 2),
    ("This Quarter", NAMEOF('Dates'[CurrentQuarter]), 3),
    ("This Year", NAMEOF('Dates'[CurrentYear]), 4),
    ("Yesterday", NAMEOF('Dates'[Yesterday]), 5),
    ("Last Week", NAMEOF('Dates'[LastWeek]), 6),
    ("Last Quarter", NAMEOF('Dates'[LastQuarter]), 7),
    ("Last Month", NAMEOF('Dates'[LastMonth]), 8),
    ("Last Year", NAMEOF('Dates'[LastYear]), 9)
}

I don't understand how the slicer using the 'Dates'[Date] field works just fine, but the parameter based on the relationship of different dates joining back into 'Dates'[Date] doesn't work.  Does anyone know why?

I have guesses, but I'm not sure where to start...
1.  The Date Parameter should be based on a boolean calculated column and not dates.
2.  Somehow the USERELATIONSHIP function within the measure is screwing something up.

Any help would be great.  Thanks!
