The best way to solve a face that isn't upgrading/downgrading/offsetting correctly, is simply to downgrade it until it is all exploded to single edges, then upgrade those edges together again up to a new face. In case that doesn't work either, simply redraw a new wire (polyline) on top of the problematic face, snapping to its endpoints, then delete the old face and upgrade the new wire. Usually a face that you draw yourself is in much better shape than a face that you obtained by upgrade/downgrade.
