Unlimited Elements for Elementor - Posts List Element not respecting Yoast Primary Category on Translated Pages

Overview of the issue

When using the Posts List Element from Unlimited Elements for Elementor with WPML and Yoast SEO, the module does not display the Yoast Primary Category in translations. Instead, it shows the first category (by alphabetical order) that the post belongs to.

Workaround

Please, make sure of having a full site backup of your site before proceeding.

• Open the …/wp-content/plugins/unlimited-elements-for-elementor/provider/provider_params_processor.class.php file.
• Look for the getPostMainCategory function on line 574.
• Replace:

  	/**
  	 * get post main category from the list of terms
  	 */
  	private function getPostMainCategory($arrTerms, $postID){
  
  		//get term data
  
  		if(count($arrTerms) == 1){		//single
  			$arrTermData = UniteFunctionsUC::getArrFirstValue($arrTerms);
  			return($arrTermData);
  		}
  		
  		$arrMeta = UniteFunctionsWPUC::getPostMeta($postID,true);
  		
  		$mainCategoryID = UniteFunctionsUC::getVal($arrMeta, "_yoast_wpseo_primary_category");
  		
  		
  		if(empty($mainCategoryID))
  			$mainCategoryID = UniteFunctionsUC::getVal($arrMeta, "rank_math_primary_category");
  				
  		if(empty($mainCategoryID)){
  
  			unset($arrTerms["uncategorized"]);
  			$arrTermData = UniteFunctionsUC::getArrFirstValue($arrTerms);
  
  			return($arrTermData);
  		}
          

• With:

  	/**
  	 * get post main category from the list of terms
  	 */
  	private function getPostMainCategory($arrTerms, $postID){
  
  		//get term data
  
  		if(count($arrTerms) == 1){		//single
  			$arrTermData = UniteFunctionsUC::getArrFirstValue($arrTerms);
  			return($arrTermData);
  		}
  		
  		$arrMeta = UniteFunctionsWPUC::getPostMeta($postID,true);
  		
  		$mainCategoryID = UniteFunctionsUC::getVal($arrMeta, "_yoast_wpseo_primary_category");
  		
  		
  		if(empty($mainCategoryID))
  			$mainCategoryID = UniteFunctionsUC::getVal($arrMeta, "rank_math_primary_category");
  
  		// WPML Workaround for compsupp-8023
  		if (!empty($mainCategoryID)) {
          $mainCategoryID = apply_filters('wpml_object_id', $mainCategoryID, 'category', true);
  		}
  				
  		if(empty($mainCategoryID)){
  
  			unset($arrTerms["uncategorized"]);
  			$arrTermData = UniteFunctionsUC::getArrFirstValue($arrTerms);
  
  			return($arrTermData);
  		}
