formating month

I have created a calendar table, but when i create a month column with a format, it only gives months of January or December.  For example i'm getting Feb to June dates returning a month value of January.

The code i'm using is Date = ADDCOLUMNS(CALENDAR("01-Jan-2015","31-12-2017"),"DATEASINTEGER",FORMAT([Date],"DD/MM/YY"),"Year",YEAR([Date]),"MONTH & YEAR",FORMAT([Date],"MMM YYYY")," EOMONTH",FORMAT(EOMONTH([Date],0),"MMMM"),"END OF MONTH",FORMAT(EOMONTH([Date],0),"MMMM/YYYY"),"MONTH",FORMAT(MONTH([Date]),"MMM"))
