I hope you're doing well. There are currently now restrict layers available for the inner layers. Naming a layer with the word restrict in it, won't do anything.
The best that you can do at the moment is draw a cutout polygon on the inner layers to not fill part of a polygon. This is pretty easy to do, just draw a polygon and then look at it's properties set the fill type to cutout.
Let me know if there's anything else I can do for you or if I have misunderstood the question.
