glob expression excluding resources not working

The example:

• Include all servers under the group Production and child groups under production, except any servers under Production/Network/Servers: Production/!(Network/Servers)

from: https://www.logicmonitor.com/support/terminology-syntax/glob-expressions

does not work. 
If I do something like !(Vmware)in pretty much any field doesn’t seem to work, whatever I’m trying to filter (in the Alerts pane in this eg) anything with VMware still turns up, in my case I’m trying to filter the Resource Groups heading. If I type (Vmware) in the Resource Group filter only Vmware alerts are returned .

Any idea why this glob expression doesn’t seem to work???
