WPML Translation

HI! I am experiencing some translation problems of your plugin in my website https://lacanapalegale.it/: how can I translate the accordion of faq?
for now i have solved by making two different shortcodes that i insert, one in italian and one in english, but this solution creates problems with wpml, because every time i modify the page where the faqs are presented, the shortcode returns the original one in the translation. how can i solve it?

Thank you
