Singular Text Description

Hello.
You said that the SEO meta description is similar to the one shown in the source code of the affected page, but it is not. That’s the problem anyway. What could be the reason why Rank Math in WordPress transfers the text description it displays differently to the source code it sends?
I sent the sample page address and images again, thank you

Hi.
I don’t want to use this method because I had a bad experience with giving out my login information before. Apart from that, I can look at all the details you want from me and give them to you. If you do not want this method, I will continue to manually enter the descriptions of the articles (4,105 pages) one by one.
Thank you.

Hi.
I used the Health Check & Troubleshooting plugin and found that the problem still persists.
To be sure, I set up a new WordPress (6.4.1) site with Xampp on my computer and only installed the rank math seo plugin.
By adding a new post, I copied all the blocks of the last post on my site and pasted it into the new page.
Again, the snippet description in the post editor seemed correct. When I saved and viewed the article, the <meta name=”description” in the source code appeared incorrect, as I wrote to you before.
If you want, I can give you the short and simple text I pasted on the new page for you to try.
Thank you.
