Prometheus relabeling broken (relabel_configs unmarshal errors)

I have updated today my PMM2 server and i get yml parsing errors:
/srv/logs/pmm-managed.log

line 21: cannot unmarshal !!seq into string

line 41: cannot unmarshal !!seq into string

line 43: cannot unmarshal !!seq into string

line 45: cannot unmarshal !!seq into string

That lines are relabeling ones in my custom prometheus configuration file:

/srv/prometheus/prometheus.base.yml

[root@3550a92c2086 opt]# cat /srv/prometheus/prometheus.base.yml

scrape_configs:

• job_name: blackbox80
  params:
  module:
• http_2xx
  scrape_interval: 1m
  scrape_timeout: 10s
  metrics_path: /probe
  scheme: http

static_configs:

• targets:
• www.alfaexploit.com
  metrics_path: "/archive"

relabel_configs:

• source_labels: [__address__]
  target_label: __param_target
• source_labels: [__param_target]
  target_label: instance
• source_labels: [__param_target]
  target_label: node_name
• target_label: _address_
  replacement: grafana2.adsalsa.net:9115

In previous version it worked without problems.
