[Closed] Trnslate strings of plugin

Hello, I installed the plugin "Conditional Checkout Fields for WooCommerce" and I can't translate its strings of the checkout fields (I attach a screenshot). I looked in WPML>STRING TRANSLATION and since I can't find the strings there I tried the option "Strings in the theme and plugins" scanning everything and also "translate texts in admin screens" but I can't find them.
Can you please help me?
