Question The LOD group not working in terraint pain tree

I have an warning in terrain when adding an tree Prefab with full Lod to the paint tree: "The selected tree does not have an LOD group, but has a hierarchy of Mesh renderers, only MeshRenderer on root GameObject in the trees hierarchy will be used. Use a tree with LOD group if you want a tree with hierarchy of MeshRenderers"
Cant understand this, because my tree prefab already have and LOD group component.

Have some image below, thanks for reading.

 

Running into the same issue, I seem to have set up the tree with an LOD in the prefab asset and assigned all the mesh renderers, but still Terrain gives me the same error as the above screenshot. I'm in URP in 2020.3.13f1 if that helps.
