[Risolto] UX Builder Blocks not translated

Background of the issue:
I added 2 new blocks using UX Builder to my home page on link nascosto and translated and saved them using WPML.

Symptoms:
The new blocks do not appear on the homepage. The homepage is partially in Spanish and partially in English. On the translation page, all blocks are visible and translated, but some don't appear on the page at all and some appear in English.

Questions:
Why do the translated blocks not appear on the homepage?
Why is the homepage partially in Spanish and partially in English?
