Latest news general entry missing into the customization

I’ve just installed and updated the Illdy theme, now I’m trying to customize it, but I already have a problem.
In the “Latest news” section there is a subtitle which says
If you are interested in the latest articles in the industry, take a sneak peek at our blog. You have got nothing to loose!
I’ve found where to edit the “Latest news” section (appearence > customize > front page sections > latest news section), but there I can only edit the title and the button text, there is no way to edit or completely remove that subtitle.
Is that a bug of the latest version or am I looking in the wrong place?

Update: I’ve edited the code of the file themes\illdy\inc\customizer\panels\latest-news.php and forced the field to edit the general entry to appear.

Why doesn’t it appear with the original code?
I am the site admin and I have Illdy Companion active (those are the 2 condition checked to decide whether to show or not the field).
