In General Preferences, look for the last setting on the page: "Show full hierarchy, using separator". It looks like your separator string accidentally got changed from the default " : " (space-colon-space) to the text "Determine linkage of accuracy to skill…".

(We see this happen from time to time; that's the only text field on that preference pane, so it's very easy to accidentally paste or type into it when that window has focus, when you meant to be pasting or typing into your database.)

You can press the "Reset" button to reset all the settings on that pane to their default, or just type " : " (space-colon-space) back into that field. (Or choose some other separator if that's your preference.)

Hope this helps!
