I have created a surface where no ghosting can be placed slightly away from the center point（Approximately 1500）I can place the entity normally, but this prompt appears when placing the phantom，May I ask where I should modify?

Is no one willing to help? It has been bothering me for a long time
When I stand at the (0,0) coordinate, clicking on the black area displays the area outside the map, while when I stand at the (1500,0) coordinate, clicking on the area outside displays the unknown area.
Where should I set up to make the unknown area disappear
