Single blog post: How to remove headline in Pro 1.2.2?

Dear Themeco-Support,

I updated Themeco Pro to version 1.2.2 and would like to remove the headline and featured image of single blog posts. I used following code in global css:

.single-post .x-header-landmark {
display: none;
}

.single-post .entry-featured {
display: none;
}

While the image is removed, the headline still remains. Did the class name changed for the blog post heading since the latest update? Or how can I solve this problem?

Hi There,

Please also add with this CSS:

.single-post .entry-header {
    display: none;
}
