Fluentd does not write logs in one file

Question

I would like to ask, if someone can help with this problem? I would like the fluentd write logs to a single log file, and not create a new one.For example.

The fluentd, every 30 seconds records the logs for the whole day and keeps them in a per %Y-%M-%D folder. The next day, he writes another file to another folder. In the docks, I met the option of the Append file, but it does not work as it should and continues to create files. What could be reason?

<source>
  @type systemd
  tag values
  path /var/log/journal
  matches [{"_SYSTEMD_UNIT":"docker.service"},{"_SYSTEMD_UNIT": "nginx.service"}]
  read_from_head true
  <storage>
    @type local
    path /var/log/fluentd/fluentd-journald-cursor.json
  </storage>
  @label @INPUT
</source>

<label @INPUT>
  <match values>
    @type rewrite_tag_filter
    remove_tag_prefix values
   <rule>
     key        CONTAINER_NAME
     pattern    /(.*)/
     tag        $1
   </rule>
   <rule>
     key        _COMM
     pattern    /(.*)/
     tag        $1
   </rule>
   @label @OUTPUT
  </match>
</label>

<label @OUTPUT>
 <match **>
  @type file
  path "/var/log/fluentd/host-#{Socket.gethostname}-${tag}/%Y-%m-%d/"
  format json
  time_slice_format %Y%m%d%H%M%S
  <buffer tag,time>
    @type file
    path /var/log/fluentd/logs/ 
    timekey 10S 
    timekey_wait 20S
    chunk_limit_size 256m
  </buffer>
  append true
 </match>
</label>

sudo ls -la /var/log/fluentd/host-node1-node1/2022-05-04/
