I have literally never heard the term 'tabular figures' to refer to a fixed width font. The font they're using is "Varela Round" which isn't fixed width to begin with; so whether it's missing or not is largely irrelevant. edit: another comment indicates that tabular numbers can be a feature of even a non fixed width/monospace font. Dunno if Varela Round uses those.
