Xnormal texture map-size bakes out small resolution

juyan16

Hey, new when it comes to Zbrush and baking maps. I'm trying to bake a texture to one of my meshes in Xnormal but the map that comes out is always half the size I want it. I've got my document size set at 8192x4782 in Zbrush, which is the same size of the texture I want to bake. But it never comes out at that size in Xnormal. I posted screens of my settings. Someone please help.
