Not working with Divi

HI,
I am using PPWP with Divi and want to protect a part of a page. When l go to Visual Builder and insert the shortcode in a Code module at the top of the area l want protected l see a message that says the free version does not support Custom Templates. I am using the default template in the page editor and you say that it works seamlessly with site builders such as Divi. Could you please advise on what l am doing wrong. Thanks.
