Need help with fire and smoke bug

Hi, i really need some help please. I’ve been trying all day just to make some fire appear behind some smoke, and although it seems to work fine in other peoples tutorials, i cannot replicate it myself. it is driving me insane.

This happens every time, the flames are always visible, as if they were on a layer in front of the smoke.

any help would be much appreciated.

  1. is this true in the render or just in the 3D view?

  2. Maybe post a blend? It’s hard to help you from two screenshots that don 't show any of your smoke settings or material settings.
