No new Network name in Network List in my SSL VPN connection

Hallo everyone!
I have build and use a SSL VPN connection. It works, and all thing are ok, but one problem: I need to grant access not to all my subnet network, but only for a part of my subnet. I have created a new network object with a range of ip addresses that i want to share, but this network name is not visible in the list "Selectable adressess obiects". So I can't choose this network. Because of this, I must share my all subnet, but this is not good. Where is my mistake, what I am dooing wrong? Why I don't see my network_name with range of IP adressess in a selection list for "Network List"?
Regards for all!
