title: Grafana-loki not showing labels of all the deployments
body: <p>I somehow broke my Grafana+loki+promtail setup and was not able to fix it.
  In grafana, I am seeing only two values in app labels. It supposes to show 21 values(it was working fine some days back)</p>

  <p>I also checked the promtail as well I see all the targets is having this labels <code>app=&quot;xxxxxxxx&quot;</code>
  This mean promtail is adding the label on the logs but why its not showing in Grafana?</p>
