ADM import function : too many objects


I’m currently using the import ADM file function to create a session. I noticed an inconsistency.
In terms of ADM, I have a file with one program, and 3 audioContent, each one containing 1 audioObject.
When I import the file, Nuendo implements 1 folder for the program. In this folder, there are 3 folders for each audioContent. Everything is still Ok.
The problem is that in each of the “audioContent folder” I find all of my 3 ojects when I should only find one.
Therefore I have way more tracks than I should. Any idea ?

Thank you for you help,
