Different result format on different computers with same XMLA provider

Heya,

I have the same cube on two different computers. Same OS. Same XMLA 
provider.  One one computer, the XMLA results seem to follow the spec:

   <AxisInfo name="Axis1">
      <HierarchyInfo name="Test Location">

But on the other computer, the results come back as

   <AxisInfo name="Axis1">
      <HierarchyInfo name="[Test Location].[Standard]">

I am sending in the same query.  Is there some other setting which may be 
different between these two computers?

Chris
