Hi there, that is an error in the payload. You actually need to put that key into Per-App VPN payload. We have a bug tracking that fix. Essentially you'll want to add that key to the Per-App VPN payload and then add a corresponding key to the app that should use the cellular slice. If you're still having issues please file feedback so we can investigate further.
