Not all VMs being monitored

Not all VMs being monitored

I have a new install of VM Manager Plus. It discovered the vcenter server and everything seems to be working except not all of the VMs are being monitored. In the vcenter section my server says that there are 18 total VMs and 8 monitored VMs. Most of the missing VMs are powered on and listed in the virtual machine list under the vcenter server but there is no status on them and I can't select them. Also they don't show up in the dashboard summary. How do I get all of the VMs to be monitored?

Thanks.
