As for the first one, those tags were already represented on the National Wildlife refuge and Wilderness multipolygons. I decided to remove them from the island as having them on both features seemed redundant and confusing. Let me know if you disagree.

As for the second one, it looks like the JOSM autofill feature got the better of me. I've fixed the issue but feel free to look it over and let me know if you find anything else.
