Print Organizer not adding multiple files?

I am using V8i SS3 and when I try to add more than one file to the Print Organizer, either 1 at a time or multiple files at once, it only adds one file and no other files are added. If I try again it will not add any more files so I can effectively only ever have one file in the print organizer. Also, I cannot edit any existing pset files if I open one up in print organizer. Does anyone else have this issue and hopefully a way to solve it?
