Calendar does not tabulate correctly

[appley922]

Dear all, 

I am trying to organize "inventory quantity by month" into a matrix visual, but it looks like the mapping of dates to Calendar is not right. Please see below screenshot for more. 

Top visual: "Month" is taken from my Calendar table

Bottom visual: "Report Month" is taken from my inventory table

Why is the total quantity the same, but the monthly breakdown differ? 

Appreciate any help possible! 

FYI - this is the formula for my Calendar table,

Calendar = ADDCOLUMNS (CALENDAR(DATE(2017,07,01),DATE(2020,06,01)),"DateAsInteger",FORMAT([Date],"DDMMYYYY"),"Year",YEAR([Date]),
"Monthnumber", FORMAT ( [Date], "MM" ),
"YearMonthnumber", FORMAT ( [Date], "YYYY/MM" ),
"YearMonthShort", FORMAT ( [Date], "mmm/YYYY" ),
"MonthNameShort", FORMAT ( [Date], "mmm" ),
"MonthNameLong", FORMAT ( [Date], "mmmm" ),
"DayOfWeekNumber", WEEKDAY ( [Date] ),
"DayOfWeek", FORMAT ( [Date], "dddd" ),
"DayOfWeekShort", FORMAT ( [Date], "ddd" ),
"Quarter", "Q" & FORMAT ( [Date], "Q" ),
"YearQuarter", FORMAT ( [Date], "YYYY" ) & "/Q" & FORMAT ( [Date], "Q"))

Hi @appley922,

Can you share the file? You can delete most parts of the file and keep only the minimal amount that can show the issue. Please mask the sensitive parts.

I can't see the [Month] from the Calendar table. 

Does the inventory table have more than one date column? Please try with the two date columns that connect the two tables. 

Best Regards,
