[Risolto] [URGENT] Product categories duplicate issue

Background of the issue:
I am trying to fix an issue on my website link nascosto. The site is in Dutch by default, and it works fine in that language. However, when I switch to another language, such as English, I encounter a problem on the product category pages.

Symptoms:
On the English version of the product category page (e.g., link nascosto), there are duplicate categories displayed on the left side.

Questions:
Can you please check why there are duplicate categories on the English version of the product category page?
How can I fix the issue of duplicate categories when switching languages?...
