After further investigation, we have identified the issue. When selecting a filter to include, if you choose 'All Computers', you may actually be selecting the filter that is not populated with any computer resources. To work around this, select both 'All Computers' filters that show up in the list. Only one of these is supposed to be visible so that is what we are looking to fix. Once you select a filter that actually has computer resources in it, the task works great...:-)
Since the Organizational Hierarchy task uses this Network Resource Location task it should automatically fix that as well...
