Distant Content Clipped When nDisplay Is Enabled

When using Cesium for Unreal to display terrain and OSM maps, adding nDisplay to level causes distant map content to disappear (resembling far-clipping). This results in only a blank space when attempting to obtain a national or global view. Everything works perfectly without nDisplay. I’ve enabled “Follow Local Player Camera" in nDisplay, but the issue persists. There seems to be no relevant setting in nDisplay to adjust this behavior. What mechanism is causing this?
