I have run across this while I am creating workflow requests.  I create a new section for a request and there is the ugly “Section” text being displayed on the screen.  I used to suggest that you go to the Label section for the field and change the color to white.  This worked for many of the screens that an Employee may use when they switch Styles in their preferences.

In some styles, this was not a good solution.

Today, I am recommending the use of the value “&nbsp” into the text.  This code is simply an empty character that is used in HTML code.
