Here is a link to the thread describing the issue I'm having: http://formidablepro.com/help-desk/conflicting-css/
Link to the form on my page: http://www.aspiredenver.com/aspire/contact/
Basically, something in the shortcodes CSS is causing the styling of the form to be 'filtered twice' according to the developer of the plugin. I've tested with another theme and can confirm it's Propulsion causing this and not another plugin. When I remove the shortcodes, the styling is fine. This is not only an issue with the form plugin, but appears to cause issues with the use of <h-> (webfonts) tags within the shortcode tags as well.
A link to the home page showing the <h-> tag problem is here: http://www.aspiredenver.com/aspire/
All of the blue headings have the same <h3> tag as the headline 'Do Not Remove'. Shortcodes start below the horizontal rule.
