The Fontanelle - Via Chiesa as I mentioned is actually listed in your change set relations list. By consequence the bus stops shown on the wrong side of the road versus route direction belong to the route in the opposite direction (of which they are on quick check already a member, but also a bunch of stops mapped but not linked to the route.)

With what  I know now, lots of roundabouts need splitting where the routes do a full loop but that's of lesser concern, a laborious thing to do without the right tools and daily practicing.
