Nested prefabs with LODs Issue

Hi, I have an issue (Unity 2019.2.12f1) regarding Prefabs - Package Validator shows this error:

“We do not allow prefabs that contain a mesh with “LOD” written in the name but do not contain a “LOD” elements or more than 1 mesh attached. Please make sure that “LODs” are correctly set up in the prefab. Refer to this guide to set up your “LODs”:http//docs.unity3d.com/Manual/class-LODGroup.html”

Does Unity allow nesting prefabs that contain LOD Groups?
Example when it happens:
House facade is split into several pieces (with LOD groups) - Prefabs are made out of these.
Then a BLOCK of buildings is assembled of them.
Next a prefab is made out of this BLOCK. (Drag and drop BLOCK - from scene into project folder) -
This should be a regular way to create a prefab containing nested prefabs right?
However this last step causes Validator to call this error.
Is this even an issue / whats problems could it cause for user?
Regarding this an error this might cause for package rejection right?
What are potential solutions / what am I doing wrong?
(I red documentation (on LODGroups, Prefabs) already bud have not been able to find solution)

Thanks.

Hi,
the package that was showing this kind of validation error while being uploaded to asset store had just been accepted by Unity (now in unity 2019.2.14f1).
So apparently it is a non issue and Package Validator was showing just some king of warning.
