Problem: You are experiencing an issue where categories related to posts disappear intermittently, despite correct translation configurations. Solution: First, determine if the disappearance occurs in the translated versions or the original language as well. Next, try deactivating all non-WPML plugins temporarily to check if the issue persists. This step helps identify if there is a plugin conflict causing the categories to disappear. We recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins.
If the problem continues, we suggest opening a new support ticket for further assistance. You can do so at WPML support forum.
