[Plugin: WP Category Post List Widget] Hide title if category list is empty

Hi, I use the widget to list open jobs on a website. These days, there often are no vacancies so the list can be empty – so only the title is visible. I’m trying to figure out how to make also the title (category) disappear if there are no vacancies listed. My programming skills are very limited so I am clueless trying to make sense of the code… but I keep trying.
