Thanks for testing. There's also a "Show doors" in the map context menu. I doubt it would override filtered either, but maybe you could remove it from filtered and just toggle the display based on whether you want them on or off. They would still show up in the spawn list, but I would think that should be fixable with a custom category. Not a perfect solution, but maybe a functional work around for the time being?

Since it would be a pain to remove it from the global and add it to all zone filters except for one, it does sound like we need a way to override global filters at the zone level. Added to my list.
