NSArrayController bindings -- duplicate data?

Subject: NSArrayController bindings -- duplicate data?

I have an set of unit types in my app which are managed by a fairly simple controller. I also have a master-detail interface in my preferences for changing the display name of units (for instance gal. instead of gallon). I'm using an NSArrayController to fill this interface and it is bound to my unit controller's set (data key path is "unitController.units" bound to my app delegate). The problem is that it seems the Array Controller is copying the set, so when I try to read a value elsewhere in my app after I have changed it in the preferences I get the old data. Any ideas what I might be doing wrong?
