[Dx4win] Creating Group Names/Selections

[Fred - NA2U]

I reinstalled DX4WIN following a hard disk failure.  Fortunately, I had backup copies of my various logs.  

I had group numbers created and the group numbers still show but I have loat the Group Names and Selections.  If I click on "Filter" both "Selection" and "Edit Group Names" are grayed-out. 

How can I recreate my selections and group names?

73 from the desert and thanks,
