PR: Axis and generic models export and re-import. Duplicated and rotated

### Problem Description

... Hello.
I have configured a modell in Revit2025, Coordination generic modell, and Project Basis Point all over the internal origin. Then added geographic north rotation.
I export the IFC with internal coordinates and geographic north and everything is OK in every IFC viewer, but when I re-import this IFC in Revit, all models are ok, except there are duplicates of the coordination object and of the axis raster, and both are rotated AND WITH THE SAME IFC GUID...
When I go into the "container" ifc.RVT the duplicates are there. If I erase them, and go back to the host model, and reload the IFC these rotated duplicates no longer appear.
How can we avoid this?

Thanks in advance!

### Revit Version

2025.0.x

### IFC for Revit Addon Version

25.4.0

### Windows Version

10 22H2

Reproduce the reported export and re-import using Revit 2025.0.x, IFC for Revit 25.4.0, and Windows 10 22H2, with internal coordinates and geographic north enabled. Inspect the host model and the ifc.RVT container for duplicated coordination and axis raster objects, checking their rotation and shared IFC GUID; done means re-importing no longer creates those duplicates.
