Remove title block from all posts

Greetings,

The difference between pages and posts are sometimes frustrating:
“Remove”, or, “hide title” on Pages means an entirely different thing on Posts.

It removes the title block entirely from the Pages. (That empty space between the main header and the first element of your content.)

To remove it entirely on the Posts, I was referred to “x-header-landmark”. (Scrolling highlights the entire section I want to remove) Changing it to “none” only removes the space and not the breadcrumbs, etc. It does not remove the block entirely. (I’m testing this in the elements panel to see the effect)
Only when I delete that snippet entirely does it remove it entirely. Here’s a URL to a blog post:
http://themetamodern.com/warrior-spirit/

Not sure what to do at this point. I’m using X Theme – Renew stack. I know you’re not supposed to delete anything in the template, right? But “none” doesn’t do it.

I have the site backed up so would deleting it be a proper course of action?

Thank you for any advice.

Eric
