That's this problem:


I would avoid \addfontfeature. The combination of such features
doesn't always work.  Some months ago I had the problem that a
feature added this way appeared only randomly every second


\setmainfont[VerticalPosition=Superior]{Linux Libertine O}

instead. Or define a new fontfamily.
