Background of the issue:
I am trying to manually adjust individual texts, PDF links, and YouTube links on a German page that has been translated into Spanish using WPML. These adjustments are done in the Advanced Translation Editor (ATE). The issue can be seen on this page: hidden link
Symptoms:
Text changes are only partially reflected on the Spanish page. PDF media links embedded in the page design do not appear at all in the ATE, even though they are visible on the page. YouTube links are not correctly displayed on the Spanish page. This is not a caching issue, as the problem persists in an incognito window. Example page: Spanish page: hidden link. YouTube links: German: hidden link, Spanish: hidden link. The links and text changes are saved correctly in ATE, but they are not reflected on the Spanish page.
Questions:
Why are my manual text changes only partially reflected on the Spanish page?
Why do PDF media links not appear in the ATE?
Why are YouTube links not correctly displayed on the Spanish page?
