Proper Use of TNaming

I have a situation in which I go through the following steps:

1. Create a Box using BRepPrimAPI_MakeBox
2. Add the Box and all the Faces to the Data Framework using TNaming_Builder::Generated()
3. Select Edge 3 on the Box using TNaming_Selector::Select with the Box as the Context Shape
4. Fillet Edge 3 on the Box using BRepFilletAPI_MakeFillet
5. Add the FilletedBox to the Data Framework using TNaming_Builder::Modify and TNaming_Builder::Generated as appropriate
6. "Resize" the Box by creating a new Box2 using BRepPrimAPI_MakeBox
7. Add the resized Box2 to the Data Framework using TNaming_Builder::Modify and the original Box as the OldShape

So, at this point, I try to get back a reference to Edge 3, which has now changed since its context shape was changed. However, whenever I use TNaming_Selector::NamedShape()->Get() on the Label in which I stored the selected Edge, I end up getting an Edge that is not in the resized Box2. Am a missing some step in adding data to the Data Framework that is needed?

Any help would be appreciated.
