Tags don't work on the CSS tab

Hi!

I’m testing this plugin to purchase it, but I found a bug. This refers to the section Creating a shortcode.

This is the content of each tab:

SHORTCODE SETTINGS

Element Name: Highlighter
Category: tutorials
Short Code: dc-highlight
Type: [shortcode]content[/shortcode]

ATTRIBUTES

Name: color
Default: red
Info: Set the text highlight color

TEMPLATE

<span class="highlighter">{{content}}</span>

CSS

.highlighter{
	color: {{color}};
}

Then, I use the shortcode in a post.

[dc-highlight color="blue" ] My content [/dc-highlight]

BUG: The content is painted red, always! Why?

Thanks and Regards!
