Collection export as asset browser

Hi everyone,
i have a problem with object asset browser
My target is model a prop and export like an asset browser in a specific catalog

Now i want export this collection in a specific folder to show this object from all other people of my team
I go to the blender file, select only the collection and export it without any active ticks

Then all team see the object into asset browser

BUT....
if i open the file of the object exported, there is an issue
When make export the plugin create a duble link inside the file, like image

I must open this file, unlink the object outside the collection and save... But i cant do this every time

I want select the collection (with make asset browser in a specific catalog), and export it in a new file... And if open the file i want see only this collection without duplicate object or link not necessary
Is possible?

thanks

No source file or test is named. Reproduce the reported export by selecting a collection with asset-browser catalog settings, exporting it to a new .blend file, and opening that file to inspect the duplicate object link. Done means the exported file contains only the intended collection without the unnecessary duplicate or external link.
