DIsabled Computers in Home screen, OK in CLients List

Hello all,

I am new to SEP. Currently we are running 12.1.4. In the home screen we have 30+ clients that show disabled. When I go to the clients structure the computer is OK and has the latest policy installed. My question is how can I make those computers disappear from the Home Screen? It is annoying and I really want to get rid of this. 

Thanks in advanved for your help.
