date table with month name

I am creating a date table using DAX.

Every thing works except for the Month Names.  It is as if it is random. 

This is the same method for formatting date names as seen on a YouTube video. 

My first question on the Board. I couldn't find the answer this time.

Here is my DAX:

Dates_INV = GENERATE (
CALENDAR( DATE( YEAR( TODAY() ) - 3, MONTH( TODAY() ), DAY( TODAY()) ), TODAY()),
VAR startOfWeek = 2 // Where 1 is Sunday and 7 is Saturday, thus a 3 would be Tuesday
VAR currentDay = [Date]
VAR days = DAY( currentDay )
VAR months = MONTH ( currentDay )
VAR years = YEAR ( currentDay )
VAR nowYear = YEAR( TODAY() )
VAR nowMonth = MONTH( TODAY() )
VAR dayIndex = DATEDIFF( currentDay, TODAY(), DAY) * -1
VAR todayNum = WEEKDAY( TODAY() )
VAR weekIndex = INT( ROUNDDOWN( ( dayIndex + -1 * IF( todayNum + startOfWeek <= 6, todayNum + startOfWeek, todayNum + startOfWeek - 7 )) / 7, 0 ) )
RETURN ROW (
"day", days,
"month", months,
"MonthNameShort", FORMAT ( months, "mmm" ),
"MonthNameLong", FORMAT ( months, "mmmm" ),
"year", years,
"day index", dayIndex,
"week index", weekIndex,
"month index", INT( (years - nowYear ) * 12 + months - nowMonth ),
"year index", INT( years - nowYear ),
"yearsort", INT( (nowYear-years)
)
))
