Opacity bug?

Rendering a label on a bottle I'm running into an error it seems.

Where the label is 0% opaque I see an error in the specular material just behind it, a kind of reflection of sorts.

The label distance from the bottle seems to have no effect. I've raised and lowered the Ray epsilon to no effect.

Thanks for sharing the scene.
You need to use an Octane Object tag on the label, and set the General Visibility to 0, in this way the object will be completely masked to the rays, even if the Opacity in the label material is set to 1:
