Problem:
You are trying to sync products for translated product categories on your site, but when switching to German, the product categories show 0 products, even though they are linked to the Dutch categories.
Solution:
First, ensure that you update the product translation after linking the products. Follow these steps:
1. Edit the original Dutch product that contains that category.
2. Make sure that the category is assigned.
3. Add a tiny change to the text product description (you can remove it later) and update the product. You should see that product translations are requiring an update.
4. Navigate to the translation using the translation editor and complete the translation.
5. The translated German product should have the identical product parameters as the original.

If this method does not resolve the issue, consider using the bulk editing option:
1. Go to Products → All Products.
2. Select multiple products simultaneously and choose Edit from the Bulk action drop-down.
3. Change the Comments drop-down to "Allow," update the products, and then change it back.
4. Change the language to German and attempt just to update those products in bulk mode.
