Content Analysis Error

Hi,

Yesterday I noticed a few errors in “content analysis”. I don’t is it only me or the whole SEO press community is facing this problem.
Here are the errors:
* Keyword Desnity says:
We were unable to calculate the density of your keywords. You probably haven‘t added any content or your target keywords were not find in your post content.

* Wordcounter says:
Words counter is not a direct ranking factor. But, your content must be as qualitative as possible, with relevant and unique information. To fulfill these conditions, your article requires a minimum of paragraphs, so words.
0 words found.
0 unique words found.

* Interlinking says:
Internal links are important for SEO and user experience. Always try to link your content together, with quality link anchors.
This page doesn’t have any internal links from other content. Links from archive pages are not considered internal links due to lack of context.

All of them are incorrect because:
* The page has over 600+ words content
* Decent keyword density
* Good internal links.

How can I fix these errors.

Thank you
