Deprecated: Function outlining_columns_html…

I recently updated to wordpress 6.0 and woocommerce 6.6.1.
Invoice For Woocommerce 3.1.9

Now the invoice I generate are filled with deprecated messages such as :

Deprecated: Function outlining_columns_html is deprecated since version Invoices for
WooCommerce v2.8 with no alternative available. in /home/bcraftcoey/www/wpincludes/functions.php on line 5389

since version Invoices for WooCommerce v2.8! Use

At a lot of different places.

Anyone else has this problem?
