prestashop 1.7 Date not showing anywhere in my orders (PS1.7.4.2)

[Berbero]

Hi there Prestashop Gurus

I am not a developer, but an ecommerce website owner with a bit of some knowledge of software development.

My issue is simple. There is no date showing anywhere on the orders placed, or shipping, or invoices, etc. There is only a number "1" showing next to the date field.

Here is the code from AdminOrdersController.php:

 ),
            'osname' => array(
                'title' => $this->trans('Status', array(), 'Admin.Global'),
                'type' => 'select',
                'color' => 'color',
                'list' => $this->statuses_array,
                'filter_key' => 'os!id_order_state',
                'filter_type' => 'int',
                'order_key' => 'osname'
            ),
            'date_add' => array(
                'title' => $this->trans('Date', array(), 'Admin.Global'),
                'align' => 'text-right',
                'type' => 'datetime',
                'filter_key' => 'a!date_add'
            ),

            'id_pdf' => array(
                'title' => $this->trans('PDF', array(), 'Admin.Global'),
                'align' => 'text-center',
                'callback' => 'printPDFIcons',
                'orderby' => false,
                'search' => false,
                'remove_onclick' => true
            )

and see attached snapshot from the back-office.

Any help provided is much appreciated.
