Remote Desktop is always allowed!

Hi everybody,
my COMODO is setted as “Firewall Configuration”.
System is “BLOCK INCOMING CONNECTION”.
SVCHOST is “BLOCK INCOMING CONNECTION”.
In spite of all, I can connect to the RDP of the computer from another computer!
It allow the connection to enter even there is no rules that allow it!
I know that System and Svchost are Always setted to allow any OUTGOING but here I think that RDP is an INCOMING connection.
And, after that, when I am connected to the computer, in the MONITOR CONNECTION there is not any TCP IN 3389 connection active! Only OUT connections.
Please help!
