P3D v4 the exclude water Polyng doesn't work wit orbx vetcor

I modified the Koyukuk airport in Alaska.....but now I have problems with Orbx vector. Without it, I see airport very well, but using it some piece of runway is on the water! I created an exclude water Polygon using sbuilder, to draw again the coast and the water but without result...Solution? I put the file on a folder above Orbx vector...
