Problem:
You are experiencing an issue with translating specific text strings in the WooCommerce PDF Invoices & Packing Slips plugin. Despite using WPML String Translation, the fields 'Kwota netto' (Net Amount) and 'Wysyłka (netto)' (Shipping Net) remain untranslated and appear in Polish on the invoices, regardless of the selected language.
Solution:
We recommend the following steps to resolve this issue:
1- Open the

app/public/wp-content/plugins/woocommerce-pdf-ips-pro/includes/wcpdf-pro-multilingual-full.php

file.
2- Around line 297, inside the

string_translate_premium_templates_label_text()

method, replace the existing code snippet with the following:

if ( !empty($setting['label']) ) {<br />    // WPML<br />    if( class_exists('\SitePress') ) {<br /><br />        $setting['label'] = __( $setting['label'], $textdomain ); // HERE<br /><br />        $textdomain = 'wpo_wcpdf_pro';<br />        $string_name = 'PDF String: '.substr($setting['label'], 0, 20);<br /><br />        do_action( 'wpml_register_single_string', $textdomain, $string_name, $setting['label'] );<br /><br />        // Apply the translation to the string<br />        $setting['label'] = apply_filters('wpml_translate_single_string', $setting['label'] , $textdomain, $string_name);<br /><br />    // Polylang<br />    } elseif( function_exists('pll__') ) {<br />        $setting['label'] = pll__( $setting['label'] );<br />    }<br />}

3- Generate a new PDF to register the strings.
4- Go to WPML > String Translator and find the strings under the 'wpo_wcpdf_pro' text-domain.
5- Switch the string language to the default language, then translate it.
