Background of the issue:
I am trying to synchronize products between categories in both languages on my WordPress site using WPML. I attempted several solutions, including deleting and disabling the category, clearing the cache, and reinstalling clean, but nothing resolved the issue. The issue can be seen on this page: hidden link
Symptoms:
Products from another category are not displayed where they should be, leading to incorrect synchronization between categories.
Questions:
Why are products not synchronizing correctly between categories in both languages?
What steps can I take to ensure products are displayed in the correct categories?
