After Installing and trying to create a new Calendar getting error: 'DB Error: no such field'

[duncan-s-white]

CiviCRM: v6.4
Event Calendar: 4.6
Wordpress: 6.8.2

After Installing the extension through the UI and trying to create a new Calendar, the calendar is not being created and I am getting error: 'DB Error: no such field' error message.

After looking at the logs, the field in question was the is_deafult field.

I can see that my extension does have the upgrade_1004 to the database in the Upgrader.php file, so I cam not sure why this upgrade is not creating the field.

I uninstalled the extension which I could see completely removed the civicrm_event_calendar table and then reinstalled, however the is_default field was still not present.

When I create the is_default field manually tot he same spec as the Upgrader file in the civicrm_event_calendar table and then create a calendar, calendar is created, and can be displayed on the front end of my wordpress site as expected.
