Image Menu and missing PolyLang strings

Hi

Thanks for a superb theme! It’s working great on my non-profit’s website, which is in 2 languages – English and Greek, using PolyLang.

I’m trying to add an image menu to the home page. It all works great and the title strings appear in Polylang’s string translation settings page as expected, but the subtitles do not, so I get the English subtitles on the Greek home page.

Can someone help please? Happy to add a code snippet to make this happen if that’s what’s required.
