Yeah, FSX Gold here, too, DX10. Vector, Global, Pilot's Global Mesh. I found there are 2 identical elevation adjustment .bgl files, actually. The active one is in scenery/world/scenery. The one set to .off is in ORBX/Scripts/Custom.au. So I would guess it's supposed to be off. So far this is the only AP in NZ I've come across that does this but I haven't flown there all that much.
