[Risolto] Give a category a single language and associate it with two languages at the same time

Background of the issue:
I am trying to create a blog category that is accessible to several linguistic versions and use the same category to display blog posts in two different languages on two different pages. The issue can be seen on this page: link nascosto

Symptoms:
No specific issues, errors, or unexpected behavior were reported.

Questions:
Is it possible to create a blog category that is accessible to several linguistic versions?
Can I use the same category to display blog posts in two different languages on two different pages?
