How to set up RSS Wordpress?

Question

RSS

Hello, there is an rss feed on the site, I looked through the reader, this information is shown:

the domain / name of the publisher (this is indicated near the buttons: settings, update, etc.)
the title of the article (for some reason 2 times) an
excerpt of the article
link to the site

it so happened which of the plugins did this, the only place where I can set up rss is All in one seo (and when I change the settings there, nothing really changes)

I need it to look like this:
domain (this is indicated next to the buttons : settings, update, etc.)
article title
link - read in full

please help, I'm a "noob" in this thread :))
