promtail - Geoip always sets its default labels

[replay111]

Describe the bug
I have lines from firewall, where I have two fields with IP addreses: src_ip, dest_ip.
I have prepared configuration that calls twice geoip and sets custom labels, but result is that geoip always sets its own labels, and always for the last instance in pipeline.
So I did test by setting in pipeline only one call of geoip and adding my custom labels - still result is the same - all geoip labels are added by default, my label is not even visible

To Reproduce
config with two geoip:

server:
  http_listen_port: 9080
  http_listen_address: 0.0.0.0
  grpc_listen_port: 9095
  # log_level: info
  log_level: debug

positions:
  filename: /data/positions.yaml

  - url: https://loki.local/loki/api/v1/push

      insecure_skip_verify: true

      - geoip:
          db: "/assets/geo_db/GeoLite2-City.mmdb"
          db_type: "city"
          source: dest_ip
      - labels:
          dest_geoip_city_name: '{{ .geoip_city_name }}' 
          dest_geoip_country_name: '{{ .geoip_country_name }}'

          dest_geoip_timezone: '{{ .geoip_timezone }}'
          dest_geoip_subdivision_name: '{{ .geoip_subdivision_name }}'
          dest_geoip_subdivision_code: '{{ .geoip_subdivision_code }}'

    relabel_configs:
      - source_labels: ['__syslog_message_severity']
        target_label: 'severity'
      - source_labels: ['__syslog_message_hostname']
        target_label: 'host'
      - source_labels: ['__syslog_message_app_name']
        target_label: 'app'  
        

in this setup only dest_ip is tested and included with default labels.
When I remove part:

      - geoip:
          db: "/assets/geo_db/GeoLite2-City.mmdb"
          db_type: "city"
          source: dest_ip
      - labels:
          dest_geoip_city_name: '{{ .geoip_city_name }}' 
          dest_geoip_country_name: '{{ .geoip_country_name }}'
          dest_geoip_continent_name: '{{ .geoip_continent_name }}'
          dest_geoip_continent_code: '{{ .geoip_continent_code }}'
          dest_geoip_location_latitude: '{{ .geoip_location_latitude }}'
          dest_geoip_location_longitude: '{{ .geoip_location_longitude }}'
          dest_geoip_postal_code: '{{ .geoip_postal_code }}'
          dest_geoip_timezone: '{{ .geoip_timezone }}'
          dest_geoip_subdivision_name: '{{ .geoip_subdivision_name }}'
          dest_geoip_subdivision_code: '{{ .geoip_subdivision_code }}'

in loki I see geoip data with default (not mine) labels and for src_ip....

Expected behavior
get set of two data of geolocation prefixed by src_ and dest_.

Environment:

• docker
• manual
