Calendar since September Update

[CMAC_Terry]

New to the software but having lots of problems with time deminsions since the Sept 2017 update.

I've imported two cubes from SSAS and used one dataset of date to create a calender: 

Calendar Table = CALENDAR(MIN(FactJourney[Key Date Time]),MAX(FactJobEntry[Key Date.DateTime]))

then created a year column from this table: 

CalendarYear = 'Calendar Table'[Date].[Year]

I have used the calendar table to link the two date columns in my cube imports, when I try to add a year filter form the created column it displays a blank year, there are no blank years in the data?

I had this working fine before but now really struggling, other functions I also had working previoulsy seem to error now since the update, anyone else having problems?
