how do you deal with background comp

I allways use direct visibility and refractions in black so I can comp the background in post without issues; but particulary in this scene is not totally working. I have a glass reflection in another glass and obviously, i gets a black refraction and partially coronasky.
Could anyone point me in the right direcion? whay would be the proper workflow?



would it be better if I get a ticket from support?
