Adforest Subscription packages


I hired a web developer to create a classified website for me. The developer created a site with Adforest on Wordpress. Part of our agreement was to create the website with subscription packages. The theme came with basic subscription packages. Unfortunately, I was not able to modify the packages that were preinstalled, as I did not find the option to do it. I only managed to change them on Woocommerce, however, that did not change anything on the actual packages.

How can I change the subscription packages on the site? I need to be able to add additional subscription packages, change their price and features.
