KB46186: Validating an expression in the consolidation editor changes the expression

SYMPTOM:
After validating an expression in the consolidation editor a user may see the the expression change.  Specifically, this has been seen in situations where there are three or more attribute elements within a set of parentheses, the expression changes using the following pattern.

x/(n+n+n+...+n)

x/(n+n)/(n)/(n)/...?(n)

• Create a new consolidation using the expression below:
  

•   
  
  
  

  
  (({Month=Jan 2010} + {Month=Feb 2010} + {Month=Mar 2010}) - ({Month=Jan 2011} + {Month=Feb 2011} + {Month=Mar 2011}))/({Month=Jan 2012} + {Month=Feb 2012} + {Month=Mar 2012})
  
  

  
  
  
  
• Click Validate.  The equation will change to the following:
  

•   
  
  
  

  
  (((({Month=Jan 2010}  +  {Month=Feb 2010})  +  {Month=Mar 2010})  -  ({Month=Jan 2011}  +  {Month=Feb 2011})  -  ({Month=Mar 2011}))  /  ({Month=Jan 2012}  +  {Month=Feb 2012})  /  ({Month=Mar 2012}))
