Filter with system and hidden attributes doesn't work

FCXE 687: Win7

My problem is the inverse of viewtopic.php?f=18&t=6444 (Filter with attributes) which was fixed in 687. When I define a reusable filter with all unchecked except system and hidden attributes (checked) and apply the filter, hidden and/or system files don't show up, although there are some SH files in the folder. Am I doing anything wrong or is this yet another bug? Help will be appreciated. Thanks
