Wordperfect Default Format

I'm trying to establish a default format (margins, font, font size), and used the Help instructions:

Click File Document Current document style.
Enable the Use as default check box.

Problem is, it doesn't act as the default style when I start to create a new document.

What am I doing wrong???

(I run into this same problem every few years when, for one reason or another, I have to reset the document style;  but I never remember how I did it!)
