Problem:
If you're experiencing issues with manually translated product attributes adding an extra slug in the URL, which causes filters in other languages to not work correctly, especially when using the Kadence theme with WooCommerce and the Query Loop, this summary might help.
Solution:
We recommend modifying the code in your Kadence Blocks Pro plugin to handle the attribute translations more effectively. Here are the steps:
1. Open the file

/wp-content/plugins/kadence-blocks-pro/includes/query/query-indexer-woo.php

.
2. Locate line 74.
3. Replace the
Replace:

				if ( ! empty( $attribute_values ) ) {
					$attribute_values_array = explode( ',', $attribute_values );
					foreach ( $attribute_values_array as $facet_name ) {
						$facet_name = trim( $facet_name );
						$term = get_term_by('name', $facet_name, $tax_name);

						if ($term) {
							$term_id = $term->term_id;
						}

						$rows[] = array(
							'facet_value' => isset( $term_id ) ? $term_id : 0,
							'facet_name'  => $facet_name,
							'facet_id'    => isset( $term_id ) ? $term_id : 0
						);
					}

					return $rows;
				}

With:

if ( ! empty( $attribute_values ) ) {
					$attribute_values_array = explode( ',', $attribute_values );
					foreach ( $attribute_values_array as $facet_name ) {
						$facet_name = trim( $facet_name );
						$term = get_term_by('name', $facet_name, $tax_name);

						if ($term) {
							$term_id = $term->term_id;
						}
						//WPML workaround for compsupp-7812
						$languages = apply_filters( 'wpml_active_languages', NULL);
    					if ( !empty( $languages ) ) {
							foreach( $languages as $language ){
								$term_id = apply_filters( 'wpml_object_id', $term_id, $tax_name, TRUE, $language['language_code'] );

								$rows[] = array(
									'facet_value' => isset( $term_id ) ? $term_id : 0,
									'facet_name'  => $facet_name,
									'facet_id'    => isset( $term_id ) ? $term_id : 0
								);
							}
						}
					}

					return $rows;
				}

4. After making these changes, go to your default language product and click update to create a re-index for the loop.

Problem:
You are configuring links for your site using WooCommerce/WooCommerce Multilingual & Multicurrency/Shop URL and have translated the slug of the shop, category, and product. However, the product SLUG shows the default language SLUG in every language, despite the settings, while the shop and category SLUGs work correctly in any language.
Solution:
1. Go to WPML → String Translation and delete the product slug from the String Translation.
2. Navigate to Settings → Permalinks and resave the page.
3. Return to WPML → String Translation and translate the product slug again.
If the issue persists, try deactivating all plugins except WPML, WooCommerce Multilingual, and WooCommerce to check for any conflicts. Additionally, switch between the options

Translatable—only show translated items

and

Translatable—use translation if available or fallback to default language

for Products in WPML → Settings → Post Types Translation to see if it resolves the issue.
