Background Color Code Restricts Per Page Title Display Feature

United States

Tiki 15.4
MySQL 5.6
Theme Utopia

Hey folks, I changed the background color of our tiki with this code:

body {
  background-color: #5C594A;

When the code is applied in Custom CSS, it eliminates my ability to hide page title on a per page basis.
Anyone have any suggestions as to what I am doing wrong, I'd greatly appreciate some feedback.

Dispaly Pagename as Page Title is checked
Hide Title Per Wiki Page is checked

Jeez, that easy!
