Title field not seem to be working with JSON profile

[tomers]

{
  "layout": {
    "tab1": [
      {
        "command": "while true; do reset; docker logs -f kaka; sleep 2; done"
      },
      {
        "command": "while true; do reset; docker logs -f db; sleep 2; done",
        "title": "XXXXXXXXXXXXXXX"
      },
      {
        "command": "bash"
      }
    ]
  }
}

terminator --config-json ./3-row.json

I see the layout properly, including docker logs, but I don't see the title
