Unreal warning

[ankitpentashield]

Hey I am getting the "Tile has a bounding volume that does not include all of its content, so culling and raster overlays may be incorrect" warning as shown in the output window for terrain tiles 0/0/0.terrain and 0/1/0.terrain and 1/2/1.terrain and because of that I am not able to see the globe correctly as shown in the pic 2 and pic 3. after some zoom level tile completely disappear and it shows artifact where imagery is stiching.
