Replace URLs inside Pages

Hi,
We have just installed a certificate in our website. So I had to migrate from HTTP to HTTPS.
I have used different plugings to replace URLS (From http://mydomain.com to https://mydomain.com).
Apart from the plugings I have directly exported wp_posts table and used Notepad++ to replace the remaining URLS and then import it again.
However, I can’t find the way to change the URLs embebbed in the pages built with Elementor.
It is quite strange because if I try to find the page_id inside the wp_posts table I see all URLS related to that page with HTTPS. But when I load the page from my website or I edit it with Elementor, it shows HTTP.
Of course if I edit the URL to HTTPS it works, but my website contains a massive number of URLs embebbed in pages. So edit one by one can take a lot of time…

Any idea why it is happening? Why the info in the wp_posts table and the info that Elementor shows when I edit a page is different?

Thanks in advance. I hope you can help me.

Best regards
