Assets not passing to Servicedesk

Assets not passing to Servicedesk

I have just set up servicedesk plus pro (30 day demo) and am slightly confused.
 
I have configured the integration with desktop central but none of the assets I have already scanned are being passed across to servicedesk,
 
Due to the fact I am probably being stupid, can someone put me out of my misery ?
