No icing in clouds for P3Dv4?

I´ve checked all the layers of the injected wx multiple times and I've never seen the icing setting on, nor have I seen the anti ice of my PMDG 777 in action (which happens automatically when icing is present, I tested it manually before posting). Is there something wrong with the software or one of my settings? I´m running the trial of the latest version with P3D v4.3 + FSUIPC + simconnect. Yes, the icing in clouds option is marked and has been this way since I Installed the software.
