Get rid of the icons and dates shown to left of blog posts

Hi
First, before making any changes, be sure to create and activate a child theme for Duena. The WordPress Codex has a great tutorial: https://codex.www.ads-software.com/Child_Themes.

Then go to Apperance -> Editor and add next code to style.css:

.post_type_label,
.post_date {
  display:none;
}
