Triple single-quotes does not generate docstring (MacOS)

[slw07g]

Describe the bug
Triple single-quotes (followed by enter) does not generate docstring, but triple double-quotes does.

Versions (please complete the following information):

• autoDocstring Version: 0.5.1
• Operating System: OS X Catalina 10.15.5 Beta
• Vscode Version: 1.45.0

Original Code (with line to generate on):

def get_member(self):
> docstring here <
        return self._member

Expected Result:

def get_member(self):
        '''[summary]

        Returns:
            [type] -- [description]
        '''
        return self._member

Actual Result:

def get_member(self):
        '''
        return self._member
