What does the Yoast SEO plugin want? "You're linking to another page with the focus keyword you want this page to rank for"?

Question

Search Engine Optimization

Dear experts, help me understand:
The Yoast SEO plugin in the page analysis gives the following text: "You're linking to another page with the focus keyword you want this page to rank for. Consider changing that if you truly want this page to rank.", it can even highlight the problematic place in the text, however, because of the Visual composer, I do not see these areas. But most importantly, I do not understand what he wants from me? What did he see as the problem?
If it’s completely plebeian: “what do I need to do to make the indicator green?” (picture attached).

Answer 1

Your page has a link to another page. The link text indicates the focus word that you use when analyzing the current page. This is bad because you are linking another page to this focus word. The uniqueness of the content is lost.

Answer 2

removed all links from the text, the error remains.
I thought that the plugin checks the entire code of the page, checked the links, with the keyword there is a link in the menu, i.e. it turns out the page on the keyword refers to itself. This is bad?
what else could it be? why does the plugin swear at this point?
