Can't build lighting for landscape Instanced meshes

So, i built a simple landscape covered in long dense grass, on top of that i used the foliage spawner to spawn 2 types of trees (from the kite demo to test the ambience) and some bushes.
the problem comes after building the lighting, on top of taking a long time, the log sends close to 40 warnings saying the following: “Warning Landscape _0 Instanced meshes don’t yet support unique static lighting for each LOD, lighting on LOD 1+ may be incorrect” and i don’t know what is wrong, or what to do to correct this, even after building the lighting, the editor tells me to build the lighting again.
A pick of the scene if it is any help.

Thanks.

Im having the exact same problem!
No one has any info??
