my repeated test dosen't show in grafan

Your question

hi dears, i'm very thanksful about sitespeed.io and enjoy it when i work with, i have written a multi scripting test with below configuration, but when i run test with one slug name it seems metrics overwritten and when i choose different slug name it's goes appear, how can i resolve this?

{
  "browsertime": {
    "iterations": 1,
    "browser": "chrome",
    "chrome": {
      "traceCategories": "-*,disabled-by-default-lighthouse,v8,v8.execute,blink.user_timing,devtools.timeline,disabled-by-default-devtools.timeline,disabled-by-default-devtools.timeline.stack,disabled-by-default-devtools.timeline.frame,disabled-by-default-devtools.timeline.invalidationTracking,loading,latencyInfo"
    }
  },
  "slug": "shouldBeUnique",
  "graphite": {
    "host": "172.31.54.69",
    "port": 2003,
    "httpPort": 18080,
    "auth": "guest:guest",
    "namespace": "sitespeed_io.desktop",
    "logReceivedData": true
  },
  "metrics": {
    "filter": [
      "coach.pageSummary.advice.performance.adviceList.*.score",
      "coach.pageSummary.advice.bestpractice.adviceList.*.score",
      "coach.pageSummary.advice.accessibility.adviceList.*.score"
    ]
  },
  "axe": {
    "enable": true
  },
  "utc": false
}

Start with the supplied browsertime, slug, graphite, metrics, and axe configuration, then reproduce repeated runs in Grafana. Trace whether the same slug and namespace cause metrics to be overwritten; done means repeated tests remain separately visible under the intended slug behavior and the result is documented or fixed.
