When trying to isolate a small amount of layers in a Culling Mask via the inspector it's important to note that toggling the mask to Nothing will set all the layers to none, including the hidden un-bound layers.
This will cause warnings as new layers are created if running in deferred, where you can only exclude a limited amount of layers from from culling masks (4).
To exclude layers you should start from Everything and work backwards.
