WPML Automatic Translation doesn’t translate special heading

Hello,
when automatically translating pages using WPML (as defined here: https://kriesi.at/documentation/enfold/translation/#span-stylefontweight-400translate-everythingspan) Everything is automatically translated except buttons and special headings.

Once the page is translated if we enter in the advanced WPM translator, you can search the string and it appears without translation, then you can translate it manually.

How can we automatically translate all page content including av_heading heading amb buttons?

Thanks in advance.
