Parking Lot Pro - Assigned Devices

For a multi site setup we separate the sites with their own parking lot. I notice that on any Additional Lots I create there is an Assigned Devices row just under the Private/Public Settings. However in the Default lot there is not one. Is this by design or more of an oversight in coding of the page? Not really an issue I don’t think. Just wondering if that’s what other people see in their default lot.
