problem on theme option posts on home page

Hello, I have a problem with theme options on the home page. When I want to select a category to present my blog space (my recent articles) at the option of "homepage / Frontpage Options", the most recent article appears in its entirety at the level of two other options of the home page: " hero content options" and "Headline promotion". When appearing, it erases everything that was previously entered in these options, but also with above the article appears a large amount of lines indicating the characteristics of the article, ex: ".elementor-146 .elementor-element.elementor-element -415Of51....". Can you explain to me why it does this? Also, I can't configure the number of item I want see appear before the "load more" button In terms of "hero content options", unlike your demo on catchtheme, I cannot put the "read full story" button in the center. He stays on the left. Also I can't find how to capitalize the first letter like in the demo. Am I using the correct option in your theme? Thank you for your attention to my request. Cordially and thank you for your help!
