Hello,
In this changeset you've added a couple of ways to the "superroute" of the wales coast path https://www.openstreetmap.org/relation/1820890 .  That already includes the Llyn coast path https://www.openstreetmap.org/relation/1820886 , so these ways don't need to be added to both (in fact, it'll cause a bit of confusion if you do).  Just adding them to https://www.openstreetmap.org/relation/1820886 will work.
Best Regards,
Andy
