Chique Pro remove page title

Hello. I have installed Chique Pro theme. I have used CSS to remove the title of each page. Example: .page-id-76 .entry-title { display: none; } However, for the Blog page, this CSS does not seem to work. As you can see here (https://stringsbeyond.com/blog/), the word "Blog:" is still showing. What can I do to remove this title? My website is https://stringsbeyond.com/ Many thanks! Vi
