Font family automatically changes to "undefined,sans-serif!important" in Chrome

Question

Recently, when I am using google chrome's developer tools, the default font-family is automatically being changed to "undefined, sans-serif" with the "!important" tag attached. So unless I add an inline style using the "!important" tag, it ignores my font family style rules. Has anyone experienced this?

I've provided a screenshot via the URL below and the URL to the actual HTML page. The reason the code is so messy is because I'm designing this to be sent through Outlook 2007 (if you know what that's all about).

Answer 1

I discovered that I had a font style extension installed that I didn't know about. After I uninstalled that, problem solved!

Answer 2

It has been crossed out, which means it has been overwritten by something else.
