What is the correct way to exclude VMWare folders from the new script netscan?

I am trying to use the netscan to discover VM/ESXi hosts within my vCenter applicances. I want to exclude a few specific folders when viewing from "VM and Templates" view.

It looks like it supports excluding folders based on the doc,

VMware vSphere Monitoring | LogicMonitor

I have added this filter attribute 'vcenter.folder' and in the scan it looks like this.

This doesnt seem to work though. Ive tried both 'contain' and 'notcontain' and neither are excluding these folders.

Any ideas?
