Double logging for workflowengine messages

Expected behavior

I would expect that by setting the flow log destination to a separate file, all the log items would go there
occ config:app:set workflowengine logfile --value=/path/to/your/flow.log

Actual behavior

Part of the logs still go into nextcloud.log

Environment

Server Configuration

OS: Linux 4.15.0-99
Web server: Apache/2.4.29 (Ubuntu)
Database: Mysql 8.0.21
PHP version: 7.2.24

Workflow engine: 2.0.0

Client Configuration:

Irrelevant I believe (can be provided)

Log in nextcloud.log

{“reqId”:“lFm1X5VCNKz3qk8JFOvn”,“level”:0,“time”:“2020-10-12T08:30:30+00:00”,“remoteAddr”:“server1”,“user”:"",“app”:“workflowengine”,“method”:“PROPFIND”,“url”:"/NCEndpoint/remote.php/dav/files//onedir/20200123141713",“message”:“Flow activation: rules were requested for operation Block access to a file”,“userAgent”:“Mozilla/5.0 (Windows) mirall/2.6.4stable-Win64 (build 20200303) (Nextcloud)”,“version”:“18.0.10.2”}

Differences:

nextcloud.log has more details in the message, but no extra details
Flow.log has less details in the message but extra fields
Flow activation: rules were requested for operation Block access to a file vs
Flow activation: rules were requested and then {“class”:“OCA\FilesAccessControl\Operation”,“name”:“Block access to a file”}

Is it useful to keep logging in two different places?
Thanks a lot for your strong solution, and for your hard work.

And this happens after the log has been set
sudo -u ncuser php occ config:app:get workflowengine logfile
/path/NextCloud/data/flow.log
