Background of the issue:
I am trying to duplicate the main language Portfolio posts and categories to the secondary language as an identical basis for translation. I followed these steps: I duplicated the secondary language posts under 'translation management' and synchronized the taxonomy categories 'Portfolio categories'. The issue can be seen on this page: link nascosto. I expected to see the original EST: link nascosto and the expected identical ENG: link nascosto.
Symptoms:
Expected to see an identical duplicate under ENG, but I see EST categories/posts under ENG language, and it's not an identical duplicate. The portfolio post type has been marked as 'Translatable', but the portfolio post type page has been overwritten with Estonian content in English.
Questions:
What could I be doing wrong here?
Why are there mixed EST/ENG posts on the portfolio page?
