Can't set log level to warn

I made following change in /etc/grafana/grafana.ini

[log]
mode = console
level = warn
[log.console]
level = warn

But I still see debug info in docker logs. Like the following

{"@level":"debug","@message":"datasource: registering query type handler","@timestamp":"2021-08-16T11:51:13.946436Z","queryType":"exponential_heatmap_bucket_data"}


{"@level":"debug","@message":"datasource: registering query type handler","@timestamp":"2021-08-16T11:51:13.946558Z","queryType":"linear_heatmap_bucket_data"}


{"@level":"debug","@message":"datasource: registering query type handler","@timestamp":"2021-08-16T11:51:13.946569Z","queryType":"random_walk"}


{"@level":"debug","@message":"datasource: registering query type handler","@timestamp":"2021-08-16T11:51:13.946579Z","queryType":"predictable_pulse"}


{"@level":"debug","@message":"datasource: registering query type handler","@timestamp":"2021-08-16T11:51:13.946589Z","queryType":"predictable_csv_wave"}

@uchihayuki did you restart grafana server in between your configuration changes?
