Unable to Remove Title from Body in TwentyFourteen

I’ve added the suggested code to the Custom CSS Manager plugin, as well as physically changed the CSS in the Theme Editor style.css file:

.entry-title {
    display: none;
}

To top it off, I also physically deleted the following code from content-page.php:

<?php
		// Page thumbnail and title.
		twentyfourteen_post_thumbnail();
		the_title( '<header class="entry-header"><h1 class="entry-title">', '</h1></header><!-- .entry-header -->' );
?>

After all three of these steps, the Home text still shows in the body of my page. I’m at a loss.

Any suggestions to fix this problem would be of great appreciation.

Thank you,

Michael.
