Fully Dynamic Lighting - still using Lightmaps?

Hi,

In one of my projects I use completely dynamic lighting. I have only moveable lights (afaik), Forced no Precomputed lighting and disabled the Static Light in the Project settings. Yet when i look at the statistics window, then 90% of the Meshes within the Scene still uses some Ressources for Lightmaps.

Is this normal, can I prevent this somehow?
