Excel 2007 : Combobox works with On sheet data validation list but not Off Sheet list

Attached is an example that I pulled from Contextures website (Grovier). There a re 3 sheets. The first sheet if the original file and all works as it should, In which the combobox attaches itself to the active cell containing data validation using one click. The lists for the data validation are contained on the same sheet.

Sheet Two: is the same thing modified such that the data validation lists (moved to sheet List) are using the named Ranges of the lists offsheet. Most of the functionality of the combobox no longer works. Namely the font change , number of items the list dispplays on click, autocomplete dont work any more.

any thoughts?
