Cheetah is annoying

Hi friends. I would just like to ask you all how does the Cheetah work.

I take few news stories from the news channels and post. But the Cheetah keeps saying that it has found similar stories.

I know that it will find similar stories, but because I have edited it, is it good for it keep prompting like that? and how to stop it from doing all this again and again.

Any suggestions would be welcomed. I want to post news from around the globe. So should I have to find them myself or I can just take the story and write everything in my words including what the person themselves said?

Here is the screenshot of what it keeps saying
