Please try the below calculation and check if you get the expected results
WHEN "YTD" THEN DATENAME('year',[Report date])
WHEN "QTD" THEN "Q" + STR(INT(DATENAME('quarter',[Report date]))-3) + "-" + STR(YEAR([Report date]))
WHEN "Monthly" THEN DATENAME('month',[Report date]) + "-" + STR(YEAR([Report date]))
