Multi upload question

Hi,
when I use the multi upload component in SC, it always create 2 records even if I transfer only one document.

My database:
id (primary key)
idDossier (foreign key)
Nom (name of the doc upload)
chemin (txt var)
element (txt var)

If I upload a doc, 2 records are created instead of one.

Does someone has already see that ?

Thanks

Sylvain
