Importing earth elevation is not creating solid terrain in Rhino 8 UI

Hello all. I am using Latest Rhino version and LD version here (6.1.0.9927). When I am trying to import a terrain through import earth terrain data, using only " creat lands terrain" option, In Rhino UI its importing as wireframe. No solid terrain seen and even material is also not being applied while changing them as seen below. i am visualizing this in rendered mode, is this a bug?

Have to use mesh command to make it solid (not able to change terrain color too)

Do we have any update on this issue?

Lands terrain objects are shown in 3D (as solid meshes) or in 2D (as contour lines), depending on the active viewport properties. You can toggle between 2D and 3D from the Document/Viewport properties, in the Edit Panel, as well as from the RhinoLands Ribbon Quick Access Toolbar (or the Lands Design 6 toolbars):
