[Closed] Issue with attribute slug in filter URL

Background of the issue:
I am using the HUSKY Product Filter plugin (v3.3.6) on my WordPress site (v6.5.5) with WooCommerce (v8.8.5) and WPML Multilingual CMS (v4.6.11). I am trying to filter products by attribute terms in different languages on my site hidden link.

Symptoms:
When I select the filter EINBAUGRÖßE > 2-DIN in German, the URL is hidden link. When I select the same filter HEAD UNIT SIZE > Double Din in English, the URL is hidden link instead of hidden link. The attribute terms are translated correctly, but the attribute slug itself is not translated.

Questions:
Why is the attribute slug not being translated in the filter URL?
How can I ensure the attribute slug is translated correctly in the filter URL?
