Hi,

Your boundary=disused is being flagged by QA. https://www.openstreetmap.org/relation/18438206
Think you need to change the tag per lifecycle methodology to disused:boundary=administrative , Thetag disused:boundary used near 6000 times per taginfo: https://taginfo.openstreetmap.org/search?q=disused%3Aboundary opposed to boundarY0disused just 100,

cheers
