Very weird behavior with Spark 2.7 ..... When I choose "show empty groups" and "show offline users" and deselect "group offline users" the roster shows many duplicate users. I have always configured spark like this because I like to see who is not online in each department, including entire departments. When I deselect "group offline users" the duplicates just move to the offline users group.
I have reinstalled spark and even deleted all corresponding files and folders for spark. We are using openfire 3.7 (server 2008).
This issue for me is on a windows 7 32bit. I am the only one testing saprk 2.7.
