Then you are using "HTML formatting" instead of "CSS formatting". You
can delete all the formatting attributes from your BODY tag manually in
Code View, make sure your preferences are set to use CSS instead of HTML
(Edit > Preferences > General > Use CSS Instead of HTML Tags), then go
back to the Page Properties and you should see the "correct" things.

Or just add this to your HEAD section:
<style type="text/css">
a {text-decoration: none;}
</style>
