Seems to add an additional line on the end of the file

[mwyld]

Everytime I run the following command it duplicates the last line.

    stamp_changelog(
        changelog_path: changelog_location,	# Specify path to CHANGELOG.md
        section_identifier: currentVersion,
        git_tag: currentVersion, # Specify reference to git tag associated with this section
        should_stamp_date: true, # Specify whether the current date as per the stamp_datetime_format should be stamped to the section identifier (default is `true`)
        stamp_datetime_format: '%F', # Specify strftime format string to use for the date in the stamped section (default `%FZ`)
        placeholder_line: new_unreleased_changelog
    )
    ```
