text: OSM relation 2516278 incorrectly designated as admin-level 6, conflicting with 2875223 (correctly admin-level 6) 2516278 must be changed to proper admin-level 8 - but the boundaries do not match the surrounding boundaries, as such it might not qualify for an admin-level at all?
  I recommend to remove admin-level for 2516278 completely until more accuracy is available.
