It isn’t missing the yellow dot, it’s just very small. And it’s (correctly) orange.
However I still think the balance of information suggests that it should be an inverted orange triangle.
Importantly, for the European map the Netherlands symbol should definitely be the triangle, and it would be untidy to have different Dutch insignia on each map.
I’m wondering how the Euro map will handle roundels; will they be 1939 or 1940? That is, will for example Denmark have a Danish roundel over which you place a German marker, or a German cross already in place? This is important when considering that many of us will want to use the map for pre-1940 scenarios, so I’d prefer 1939 symbols.
