Dreamweavers design view will not be 100% the same as it is rendered in the browser.
When I view your page, I see a lot of conflicting styles going on that may be contributing to the issue.
You have styles sheets with similar names that define the same classes.
another thing to bear in mind is that HTML Editor applies styles as classes to span elements, when I look at your source, I see:
<div id="Term"><p><span class="Term">Your First 2 month's Rent!<br></span></p> </div>
you have the Term class and Term ID styles applied here.
In Dreamweaver, the term is in bold type.
I do not see any CSS in the term class or ID to bold the text
