Rescan deletes manually added software

Rescan deletes manually added software

I added some software-assets to my inventory.
I also managed to add that same software-asset to a workstation.
But when I rescan that workstation it deletes the software-asset from the softwarelist from that workstation.
What am I doing wrong? Is it possible to do what I'm doing?

I have the latest build (7012) installed
