Hello, I have been working with some polygon data, and found a weird overlap with some polygons. Some small islands have the same polygon as the ADM2 they're contained in, some examples are here:

Nicollet Island same size as Hennepin (ADM2 containing Minneapolis)
Sauvie Island same size as Multnomah (ADM2 containing Portland)
Northerly Island same size as Cook (ADM2 containing Chicago)

I checked it on google maps, and they seem to verify that they're not supposed to have this polygon.
This is only a problem that's been seen in the US. Not sure if this is the correct spot for this to go to any relevant party, maybe others have noticed the same problem.

Hi Jacob

Thanks for pointing this out, the polygons association with these islands has been deleted.
