[Docs]: No `--chapter-filter` description

When you use command `gallery-dl <URL> -K` there is section `Keywords for --chapter-filter:` and lower there is section `Keywords for filenames and --filter:` But when you open https://gdl-org.github.io/docs/options.html there is only description for `--filter`. Is `--chapter-filter` different from `--filter and docs are missing description for `--chapter-filter`? Or they are the same and one is alias for other?
