[Closed] Wpml translation editor does not display the content to be translated

Background of the issue:
I am trying to translate my content from default English to Spanish using WPML. The issue can be seen on this page: hidden link

I have used Theme Qode Bridge with WP Bakery and WPML for more than 10 years; this is a new issue since a couple of versions ago.
Updating the original post doesn't fix the issue.
Deleting the translation and creating a new one doesn't fix the issue.
Creating new content doesn't fix the issue.
Resign or delete translation jobs neither.
Deactivating cache plugin Fastpixel and WP Bakery don't fix the issue.
I got some pages to show up the new content to be translated but had no idea I forced it.

In the translation editor, if I click save and exit, all English content will overwrite the Spanish page.

Symptoms:
In the translation editor, WP Bakery texts to be translated are missing. Additionally, the Spanish content is overwritten with English content in both the front end and WordPress editor if I click save on the translation editor.

Questions:
Why does the WPML translation editor not display the content to be translated?
Why are WP Bakery texts missing in the translation manager?
Why is the Spanish content overwritten with English content in the front end and WordPress editor?
