At this point the filter should be configured correctly. You will still need to check the package assignment and verify that the filter is being applied to the proper group or computer.
Right-click the filter package and select Assign as shown in the screenshot below. You can then select one or more groups and/or computers to assign this package to. You can also select Global and automatically apply this package to all computers, regardless of their group membership.
The same process can be applied when setting up an exclude filter. Once you've set everything up, you will need to save the configuration as well as push the configuration to the remote machines.
