please post a screenshot of the behavior you explained since I am not seeing that on our demo and your demo is not live
The link is ok now.
There are two modules on the right side.
Module number 1 (yours) shows it wrong.
Module number 2 (from another company) shows it right.
Both modules are configured the exact same way to show article titles from different categories & subcategories.
Since the site is RTL try to read the module content from right to left...
Module number 2 (from another company) shows the article titles & only the article titles.
Module number 1 (yours) shows the article title & afterwards the category or subcategory name.
