World Offset on Landscape Material Not Rendering in Level Instance

I have a Level with a Level Instance of CaMT_World_2d_Region
and this is what that level instance looks like


And this is what CaMT_World_2d_Region looks like

when editing it

The landscape material uses world position offset, but also the texture is not showing?

I have no idea what i should be looking for or where to debug this?

The Level Instance uses World Partition (To make use of Data Layers for manually loading data via blueprint)
Main Level using the instance has World Partition Disabled - to make use of level streaming (to manually load levels via blueprint)

My plan, was to have a level with a landscape, and curved via shader, for large surface areas.
This level would make use of Data Layers for loading data relative to specific locations on the landscape as user selects those locations or moves to within Xdistance.

I would have a main persistent world/level and load all other levels into as needed (in the program, users may be interacting with a 2d map instead of curved representation of that map)

Multiple levels with landscapes could be loaded and positioned according to Geocentric coordinates. And each level could beloaded/unloaded as user rotates around the center of the sphere or load all the levels, but unload all but the ase data layer in each each level its loading. And then, as camera moives closer to a level, via blueprint, tell that level to load certain data layers

Perhaps I only need World Partition and Data Layers? Or maybe need to drop Data Layers and try to only use Level Streaming?

I do not know why it would be something with material?

Or, perhaps something Level Instancing?

Ihave also converted the persistent level to world partition got the same flat result with white landscape
