[POLYLANG] Trying to register a key in the wpml-confg

Hello, the key I am trying to register is <key name=”woocommerce_price_display_suffix”/> it is the option of woo commerce to display suffix after the price, for example mine is: Incl. VAT, I want this translated in my other languages… I am using Avada theme, and I tried lots of stuff, tried to place wpml config in the polylang but that key is still not showing in string translations, tried the original wpml file of my theme, and the same result..the wpml looks like this

<wpml-config>
    <admin-texts>
        <key name="Avada_options">
            <key name="google_analytics" />
            <key name="space_head" />
            <key name="space_body" />
            <key name="header_number" />
            <key name="header_email" />
            <key name="header_tagline" />
            <key name="breacrumb_prefix" />
            <key name="footer_text" />
            <key name="blog_title" />
            <key name="portfolio_slug" />
            <key name="project_desc_title" />
            <key name="project_details_title" />
            <key name="skills_title" />
            <key name="categories_title" />
            <key name="project_url_title" />
            <key name="copyright_title" />
            <key name="gmap_address" />
            <key name="email_address" />
            <key name="woocommerce_price_display_suffix" />
        </key>
    </admin-texts>
    <custom-types>
        <custom-type translate="1">themefusion_elastic</custom-type>
        .....
