And the footnote number did not appear at the bottom.

That's correct — there aren't any footnote numbers where the actual post appears at the bottom. You can see the text of the footnote just by hovering the mouse over the footnote number in the source, and you can get to it by clicking the footnote number. So do we need the footnote number at the bottom?*¹⁷⁰⁸⁵
