I have a bunch of autosaved sessions which contain this two workspace setup. Both are anonymous meaning I haven't named and saved them. The main window is entitled "Workspace - Accordance" which is normal but the second one is called "????? - Accordance". I have no idea how it got this name. If I try to repro. this from scratch my second workspace window shows up called "Workspace 2 - Accordance" which is again normal. I've attached the saved session file in case its of any help.
