The ASCENDANTS MDX Function is returning an incorrect member when used
on a calculated member that is at the first level, level 0, of a
dimension. If the calculated member is not at the first level then the
member returned for the query is correct.

In the example below, PRODUCT is the dimension and the calculated member
MYFAVORITE is at the first level of the dimension:

   WITH MEMBER [PRODUCT].[ALL PRODUCT].[MYFAVORITE] AS
      '[PRODUCT].[ALL PRODUCT].[ROOT BEER]'

When this is used in a query for example:

   SELECT {ASCENDANTS([PRODUCT].[ALL PRODUCT].[MYFAVORITE])}
      ON COLUMNS FROM CUBE1

This query returns ALL PRODUCT for the dimension instead of the
calculated member MYFAVORITE.
