Why do I get 15 draw calls from Obi if everything is disabled?

Hi,

I disabled all my gameobjects in the scene, and the screen is black.

I have two problems:

1) When my emitter & solver's gameobject is enabled, it still counts as several draw calls, even though:
       -it is behind the camera (not shown on screen)
       -the speed of emission is zero


2) Even when I disable all emitters and solvers in my scene, I still get 10 draw calls, and this is what I see in Frame Debugger:

How do I make sure I only get those draw calls when it's emitting AND on screen?

Thanks
