Unsubscribe from expired membership

On manual change of membership (checkbox is marked in settings), the membership changes from one Mailchip list to another. Working as intended. But when I have a membership expire it doesn’t remove it from the mailing list.

Is this a feature that is built into the plugin, and it just isn’t working right?

I can see it selecting expired on line 1138 of the plugin file.

WHERE user_id = %d AND membership_id NOT IN(%s) AND status IN('admin_changed', 'admin_cancelled', 'cancelled', 'changed', 'expired', 'inactive')
