modify url .pdf

I just uploaded my staging site from https://www.staging2.tedioli.com/ to http://www.tedioli.com

I have a lot of pages like this, with numerous links to pdf pages.

After switching from staging to the “official” site, these links have not changed and the plug in does not see them and therefore cannot change them. You can help me?

The page I need help with: [log in to see the link]
