Hello. There are a few questions about filebeat 7.6.0.

While writing the filebeat, the file bit pattern is used as shown below.

-/seungdols/logs/node/server/server.log  
-/seungdols/logs/node/server/server.log.\*

And while I was working on renaming the log files, I got a question.

If it is set as above, and previously set the log file in the format of server.log.yyyyMMdd, use server.log and limit the capacity. If it exceeds 100MB, server.log.1|2|3|4|5 rotate the log file.(using log4js-node)

If you check /seungdols/apps/filebeat/data/registry/filebeat/data.json to check if the filebeat is operating normally, the files except the server.log.1 file appear in the source, and server.log.1 The file does not appear in data.json.

```json
{
  "source": "/seungdols/logs/node/server/server.log.3",
  "offset": 100000143,
  "timestamp": "2020-06-29T17:45:35.446786333+09:00",
  "ttl": -1,
  "type": "log",
  "meta": null,
  "FileStateOS": {

}, {

  "offset": 100000114,
  "timestamp": "2020-06-29T17:45:30.72386358+09:00",

  "FileStateOS": {
    "inode": 2148631082,
    "device": 2053
  }
}, {
  "source": "/seungdols/logs/node/server/server.log",
  "offset": 82133478,
  "timestamp": "2020-06-29T17:49:03.856735277+09:00",
  "ttl": -1,
  "type": "log",
  "meta": null,
  "FileStateOS": {
    "inode": 2148631083,
    "device": 2053
  }
}, {
  "source": "/seungdols/logs/node/server/server.log.5",
  "offset": 100000096,
  "timestamp": "2020-06-29T17:45:35.446786333+09:00",
  "ttl": -1,
  "type": "log",
  "meta": null,
  "FileStateOS": {
    "inode": 2148631084,
    "device": 2053
  }
},
{
  "source": "/seungdols/logs/node/server/server.log.4",
  "offset": 100000180,
  "timestamp": "2020-06-29T17:45:35.446786333+09:00",
  "ttl": -1,
  "type": "log",
  "meta": null,
  "FileStateOS": {
    "inode": 2148631085,
    "device": 2053
  }
}

```

What is the reason?

Why is the server.log file showing the same path twice?
