We replaced some products items with the new

Hi

This is the first time I use this plugin, and this message appeared to me “Thank you for using WooCommerce Thank You Page Customizer. We replaced some products items with the new item that have more options in the latest update; therefore those old products items will not work any more. Please go to cutomize to update your Thank you page. We are sorry for this inconvenience.”
do you have any idea about this message?

Thank you
