Field Parameters and Calculation Groups together?

Hi, AlexaderMilland 

I'm sorry I can't open your sample file link, I created the sample data:

Orders Table

Calendar Table

Relationship

Create calculated group:

Then put this group in Slicer view and create a new measure, try the following DAX:

IsNewDynamic = 
SWITCH(
    SELECTEDVALUE('Calculation group'[Calculation group column]),
    "ShipmentDate", CALCULATE(SUM('Orders'[IsNewShipment]), USERELATIONSHIP('Calendar'[Date], 'Orders'[ShipmentDate])),
    "PaymentDate", CALCULATE(SUM('Orders'[IsNewPayment]), USERELATIONSHIP('Calendar'[Date], 'Orders'[PaymentDate]))
)

Put this measure in visual. When you click on the slicer, the date is switched, here is my preview:
