The reason that you see this issue is that you do not have any assign resources to a pool (Default Pool).
The host that you see from the Host view is from the installation of the Windows Agent that will manage the pooled virtual machines and network resources. The next step of your installations should be:
1. Create your Network Resources (Resources->Network Resources Tab)
a. IP Address Range
b. MAC Address Range
c. VLAN ID Range
2. Assign the Network Resources to the Default Pool
3. Assign Host to Default Pool (Resources->Hosts Tab). Click on the icon that says: Assign Host to Pool
4. After you have successfully pooled the host, you will see the Pooled RAM and Pooled VMs from the Pool Views
5. Now you can attempt to deploy your Application Configuration (Library Tab)
