Landscape Missing From editor view but shows when play from here, help

UE4 doesn’t have world partition it seems. I can’t untick enable streaming…I can see all the land in world composition window. I see landscapes fine in non world composition levels, so streaming could be the issue, but why would that affect in editor view? and why all of a sudden…also, I can see the lanscapes there in the x1y1 etc sub levels which are completely dark.

even tried shall all, multiple times

still not figured it out
