autodoc duplicates class' methods

The automatically generated documentation duplicates the Methods for the Test class, as shown below. Why is this duplication occurring and how can it be stopped?

I have tried several variations within the conf.py module, but it has been to no avail. After the documentation image, there is a redacted version of this module.

class Test(object):
    """
    Something here for test.
    """

    def __init__(self):
        pass

    def fit(X, y):
        pass

extensions = ['sphinx.ext.autodoc',
              'sphinx.ext.autosummary',
              'numpydoc',
              'sphinx.ext.doctest',
              'sphinx.ext.intersphinx',
              'sphinx.ext.imgconverter']

numpydoc_class_members_toctree = False

autodoc_default_options = {'members': True,
                           'inherited-members': True,
                           'show-inheritance': True}

For anyone else that faces this issue, I was able to fix it by replacing 'numpydoc' with 'sphinx.ext.napoleon'. Additionally, I removed numpydoc_class_members_toctree = False.
