Thank you for this plugin. It's really awesome! I just found it about two weeks ago and want to keep reading so I can enter more data .

If I go to the Genre view in edit reading goal and click on the date column in order to sort by date I get the following error:

calibre, version 7.16.0
FEHLER: Unbehandelter Ausnahmefehler: <b>TypeError</b>:'&lt;' not supported between instances of 'QDateTime' and 'NoneType'

calibre 7.16  embedded-python: True

Traceback (most recent call last):

    return first < second
           ^^^^^^^^^^^^^^
TypeError: '<' not supported between instances of 'QDateTime' and 'NoneType'

In shelf view there is no problem sorting by date.

Thank you for your great work!
