The area you talk about it Nieuw Milligen TMA (part A). You can see this if you bring up the What's Here menu by long-pressing on the map. This is class E airspace from 1500 to FL65 and class B from FL65 to FL195.
I can see that we've divided up the TMA in a way that isn't shown on the other chart, which I agree could be confusing. I'm going to investigate this and see if we can represent it more like the other chart. Thanks for reminding us about this.
