Drill up vs back button on chart

[lots_of_questions]

Hi all,

I have created multiple dashboards with dimensions.  One dashboard the hierarchy is displaying with a back button (This one works correctly)  The other has a Drill up button (This doesn't work as if you click off the chart it loses the object you drilled into)

Can someone tell me how I fix the hierarchy to be back instead of drill up.  I assume it's an issue with the hierarchy, but I can't see any difference.

Ok... So here is what I found. 
If you:
- design your project with a Database, Business and Presentation Layer (namespaces) and
- place a short cut in the Presentation Layer to a folder in the business layer that contains your dimensions and
- you hide the component and children in the business Layer
then the drill down doesn't work.

However if you show the Business layer or use a shortcut of the actual dimension instead of the folder the business layer, it works.  It actually had nothing to do with the hierarchy as it works perfect in a report.
