This thread is resolved. Here is a description of the problem and solution.
Problem:
The client has numerous categories in a bilingual GA/EN setup, where categories are randomly set with their original language instead of all being set to GA as intended. Manually adjusting each category's original language for about 150 categories is impractical.
Solution:
We recommend the following steps to streamline the process of setting GA as the original language for all categories:
1. Delete the translations, keeping only the categories in the default language.
2. Create a dummy product and add all the categories to it.
3. Use the translation editor to translate these categories. If using the advanced translation editor and the categories were previously translated, they should appear translated.
4. Save the product to set GA as the default language for these categories.
5. Navigate to WooCommerce Multilingual > Categories, scroll to the bottom of the page, and click the button to synchronize the categories across all products.
Before proceeding, ensure you back up your site and perhaps start with just one or two categories to familiarize yourself with the process and check for any unexpected issues.
