Changing strait quote marks for curly ones

Hi there, under autocorrect, autocorrect options, then localized options I cant get the double quote option to accept the change to curly quote marks, when I click okay it stays the same with strait quotes which I don’t want, Thanks in advance.

So just do ⇒ Tools ⇒ Autocorrect ⇒ Apply
and further: ⇒ Tools ⇒ Autocorrect ⇒ [x]While Typing
