Can Execute Report But Fails in Query Builder

Question

I'm running into an odd issue...
I've inherited a report that was built using Visual Studio. It's going against an Analysis Services cube and the query is in MDX.
For some reason, when I view the query in Query Builder and attempt to execute the query, it throws an error. I then cancel out of Query Builder and cancel any changes. Now if I actually run the report, it runs just fine. Users have verified that the results
are correct.
I've never seen this before! I've attached the query and the error message:
WITH
SET [Selected Discipline] AS STRTOSET(@Disciplines, CONSTRAINED)
SET [Selected Department] AS STRTOSET(@Departments, CONSTRAINED)
SET [Selected Departments] AS IIF(@Disciplines = @Departments, 
  FILTER(
    DESCENDANTS([Selected Discipline], [Employee].[DISC - DEPT - EMP].[Department], AFTER), 
    NOT INSTR([Employee].[DISC - DEPT - EMP].CurrentMember.UNIQUE_NAME, "Freelance")),
  DESCENDANTS([Selected Department], [Employee].[DISC - DEPT - EMP].[Department], AFTER))
SET [TTM] AS { LastPeriods(12, StrToMember(@SelectedMonth, CONSTRAINED)) }
SELECT 
  [Measures].[Employee Hours], 
  [Measures].[Employee Hours %] 
} ON COLUMNS, 
NON EMPTY CROSSJOIN(
[Selected Departments],
[Employee].[Employee Bill Rate].[Employee Bill Rate].ALLMEMBERS,
[Employee].[Employee Level].[Employee Level].ALLMEMBERS,
[TTM]) 
DIMENSION PROPERTIES MEMBER_CAPTION, MEMBER_UNIQUE_NAME ON ROWS

[Employee Hours Time Category].[Time Category].&[Client Facing],
[Employee Hours Time Category].[Utilization Category].&[PRODUCTION])
CELL PROPERTIES VALUE, BACK_COLOR, FORE_COLOR, FORMATTED_VALUE, FORMAT_STRING, FONT_NAME, FONT_SIZE, FONT_FLAGS
The error is:
