Deferred Decal

I have a .png image that I want to use as a decal(to be visible only with dynamic lighting). So, I created a decal material, and set it up so that it did not use a Dbuffer. However, on applying this material to any deferred decal object, the decal is still visible with static light and even in the absence of any light.

(In Project Settings -> Rendering -> Lighting) I have DBuffer Decals disabled and In Project Settings -> Rendering -> Optimization) Movables in Early ZPass disabled and Early ZPass set to Decide Automatically.
