Translation is not working in checkout fields

Here i found the solution:

/wc-fields-factory/includes/wcff_checkout_fields.php

/* To render custom checkout field */
    public function wcccf_custom_checkout_fields(){
        
        $checkout_custom_meta = $this->get_fields_meta( 'custom-fields' );
        $checkout_custom_fields = array();
        foreach( $checkout_custom_meta as $name => $val ){
            $checkout_custom_fields[$name] = json_decode( $val[0], true );
        }
        
        foreach ($checkout_custom_fields as $key => $field) {

            $is_enable = isset($field["is_enable"]) ? $field["is_enable"] : true;
            if (is_array($field) && isset($field["key"]) && $this->check_login_user($field) && $is_enable) {
                $wccpf_options = wcff()->option->get_options();
                $multilingual = isset($wccpf_options["enable_multilingual"]) ? $wccpf_options["enable_multilingual"] : "no";
                if ($multilingual == "yes") {
        			/* Localize field */
        			$field = wcff ()->locale->localize_field ( $field );
        		}
                $field["name"] = $field["key"];
                $field["required"] = isset( $field["required"] ) && $field["required"] == "yes" ? true : false;
                $field["cloneable"] = "no";
                $field["for_front_end"] = true;
                echo wcff()->builder->build_user_field( $field, "wcccf", true );
            }

        }
    }

/wc-fields-factory/includes/wcff_locale.php

public function localize_field($_field) {

    	/* Determine the current locale */
    	$locale = $this->detrmine_current_locale();
    	/* Well start the translation */
    	$wcff_options = wcff()->option->get_options();
        $default_locale = isset($wcff_options["default_locale"]) ? $wcff_options["default_locale"] : "en"; 
    	if($locale != $default_locale) {
    		if(isset($_field["locale"]) && isset($_field["locale"][$locale])) {
    			$resources = $_field["locale"][$locale];
    			if($resources) {
    				foreach ($_field as $key => $value) {
    					if($key != "locale") {
    						if(isset($resources[$key]) && $resources[$key] != "") {
    							$_field[$key] = $resources[$key];
    						}
    					}
    				}
    			}
                
    			/* Remove locale property from the $_field argument
    			 * as it is no longer needed */
    			//unset($_field["locale"]);
    		}
    	}    	
    	return $_field;
    }

I hope this code useful to this community and Plugin auther will fix in next release version.

Thanks.
