Neither GADM nor Natural Earth includes the fjord in Denmark, and Marine Regions excludes it, so records like this https://www.gbif.org/occurrence/1993109931 will be reported as an issue if are located in that area https://www.gbif.org/occurrence/map?country=DK&issue=COUNTRY_COORDINATE_MISMATCH&geometry=POLYGON((10.34912%2058.11768,9.85474%2058.07373,9.49219%2057.67822,7.05322%2057.052,4.54834%2056.19507,5.55908%2055.65674,7.84424%2055.26123,9.12964%2055.14038,10.88745%2054.74487,12.40356%2054.60205,12.76611%2055.65674,11.84326%2056.75537,10.34912%2058.11768)). image_2020_09_03T14_24_30_594Z

A similar issue in Russia, near the Caspian Sea. Natural Earth's polygon is inaccurate, the Marine Regions one is accurate, and the point falls in the gap:

This is fixed by using a combined Political + EEZ layer, rather than two separate layers.
