No meta descriptions

Hello.

On all my blog pages, I have placed a description in the snippet, which is supposed to solve the issue of lack of meta descriptions, however, in the rank math analysis tool, it appears that there are no meta descriptions on any of the pages.

Similarly, in each category I have put a description that appears in the snippet as a category meta description, but still, my blog appears to SEO analysis tools (including rank math) as not having a single meta description.

When I use external analysis tools like ahref or sitechecker, etc. the problem persists and likewise one of the errors of my blog is the absence of meta descriptions.

The same happens when I find the results of my blog in google, the meta description that appears does not match the meta description that I put in the snippet.

Any idea why this happens?

Thanks in advance for your support.
