Description of the problem,screencshot would be good

I am using x-ui in a chained setup as bridge server ( (Client) <-> [ Bridge Server(with x-ui) ] <-> [ Upstream Server ] <-> (Internet) ) upstream has a ws inbound (proivided here) and on bridge i modify xray config and add another outbound

        ],
        "type": "field"
      }
    ]
  },
  "stats": {}
}

this setup works fine, but the problem is traffic calculation, I'm not sure if this is accurate but for example if total traffic for all inbounds in bridge is 10 GB total downlink would be around 40 GB

Version of x-ui

0.3.4.0

x-ui log or xray log

log is this on repeat (theres only one inbound with a single connected device at the time of log)
