Yeah that text is still not showing up anywhere on your page. I even looked at your source code and it wasn’t there either. Maybe it got deleted from your widgets page or something.
To make all of the text centered you can add – text-align: center;
to your .slider-wide
code in your css around line 1186.
.slider-wide {
clear: both;
text-align: center;
width: 100%;
}
