Question 3D asset correct LOD configuration rejected

I'm trying to publish a 3D statue asset to the Asset Store but it's rejected due to the LOD configuration.
The configuration entered for the model seems to be correct, as described in the following references:
https://docs.unity3d.com/Manual/class-LODGroup.html
https://docs.unity3d.com/Manual/importing-lod-meshes.html



For the import I inserted an FBX file with the 3 LOD versions of it inside and Unity correctly created the LODGroup for the model inside the mesh package.
The meshes within it are named with the suffix "_LODX".
The LOD0 model has the most polygons (Vertices: 6923) while the LOD2 model has the least (Vertices: 1558).
What am I doing wrong?
Below I insert the error text (in case I'm missing something) and the model configurations.
