With the Databook open go to [View], [Options]. You'll probably find that the paths are erroneously pointing to 'Technology'. Use the [Browse] buttons to go up one level, then back into [Databook], then [Templates] or [Working] as appropriate.
Close the databook, and it will be OK when you re-open it.
Note that the databook only checks one library folder at a time. Which path is used is determined by the component library currently selected in the library manager.
