SSAS Calculated Member Aggregation Issue

问题

I have a very simple Calculated Member:

CREATE MEMBER CURRENTCUBE.[Account].[Account Parent].&[NA_1].[Beginning Subscribers]
  AS -[Account].[Account Parent].&[Beginning_Subscribers]

However, the Parent doesn't seem to calculate or simply ignores the Calculated member in Excel. See below:

It should look like this:

Account Dimension

This is the MDX on the Excel side:

Select /* Grid - 'Sheet1'!$A$1 */ Non Empty {[Calendar Month].[Calendar Month Parent].&[2018-11],[Calendar Month].[Calendar Month Parent].&[2018-12]} On Columns, Non Empty AddCalculatedMembers ( DrillDownMember ( AddCalculatedMembers ( {Descendants([Account].[Account Parent].&[Net_Mig_1],[Account].[Account Parent].&[Net_Mig_1].Level,AFTER)} ) , { [Account].[Account Parent].&[Net_Mig_1],[Account].[Account Parent].&[NA_1] } , Recursive ) ) On Rows From [TEST CALCS] Cell Properties VALUE
