This thread is resolved. Here is a description of the problem and solution.
Problem:
You have a WooCommerce product that you only want to appear in the Danish language, but it is showing in English and German as well.
Solution:
If you're experiencing this issue in the backend and can see the product in other languages there, we recommend you go to Products → All Products, switch to the desired language, and delete the product translations from those languages.
However, if in the backend you only have the product in Danish, but on the frontend it still appears in other languages, then please go to:
WPML → Settings → Post Types Translation
and set Products (product) to:
“Translatable – only show translated items”
This will ensure that products only appear in languages where an actual translation exists.

We highly 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 issue persists, we encourage you to open a new support ticket at WPML support forum.
