Promtail won't extract all labels

Hi I try this promtail-local-config.yaml:


pipeline_stages:
  - match:
      selector: '{job="varlogs"}'
      stages:
      - regex:
          expression: "(?P<wildflyerrors>WFLY[^:]+):"
      - labels:
          wildflyerrors:

but it won’t extract all lines that contain errors:

Any Idea?
Thanks
