--hide param doesn't work with --raw output

I have tried: 
``` bash
concurrently --kill-others "npm run build:watch" "npm run start:pm2" -r --hide "0"
# OR 
concurrently --kill-others "npm run build:watch" "npm run start:pm2" -r --hide 0
```

But hiding works only when I remove the `-r` (raw) param.

Sorry if this is intended behavior.
