Hi @worldet,
In the override layout section of the JA Blockk template, we split the Introduction and Details sections of the article into two parts to create special layouts. For articles without an Introduction section, it will be displayed twice, as shown on your website. Therefore, you need to add a Readmore tag at the beginning of the article to avoid displaying it twice.
I've added the Readmore tag to the article on your website to fix the duplicating issue.
