Hello,
I think that there might be a bit of a problem with some of the relations here - https://www.openstreetmap.org/way/137279112 overlaps with https://www.openstreetmap.org/way/375867813 now, which means that relations such as https://www.openstreetmap.org/relation/11047400 have overlaps and have fallen out of rendering databases.
The solution might just be as simple as deleting https://www.openstreetmap.org/way/375867813 and checking that all relations that were in it are OK afterwards (perhaps by using the JOSM editor's validator).
Best Regards,
Andy
