seo – Why doesn't Google Search Console get the back bio-link in my blog?

I wrote a few blogs, in order to create back-links for my website.

One of the websites that I have used is c-sharpcorner.com

I have my profile page: my profile page on c-sharpcorner

And I wrote the following three blogs (on c-sharpcorner):

  1. work with files and folders in s3 using aws-sdk-for-net
  2. submitting a form to different action methods in asp-net-mvc
  3. how-to-define-custom-password-validation-rules-in-asp-net-mvc

All these 3 blogs contain a link to my website at the bottom of the page:

But when I open Google Search Console, only one link from c-sharpcorner the domain points to my website:

Why doesn't Google Search Console take back links from my blogs? One of these blogs has been viewed 20,000 times and appears very high in Google search results … and has been there for 6 months.
