duplication of project bad referencing of files

Hi everyone,
I just noticed that when I created a duplicate of a working project.
If I made any changes in the new duplicated blender scene (added new object) and saved both the blender file and exported to assets the json and bin file, that no new object appeared in the preview.
I have subsequently tried to make the change on the original blender scene in the original project folder and now the object appears on both projects.
Clearly the duplicated project seems to still be referring to the original bin, json etc files.

Is this something that others have spotted or have you amended this is a new update?

many thanks
