Was just using the Chrome dev tools, to see why both were colored blue (active), however ...
Wow, in Chrome if you look at source code, only 1 is marked active:
<a class="list-group-item" href="http://edmontonkids.com/More/Articles/Fire-Safety">Fire Safety</a>
<a class="list-group-item active" href="http://edmontonkids.com/More/Articles/Fire-Safety-Plan">Fire Safety Plan</a>
However, using the Chrome development tools, both are marked active
Using FF, source code shows only 1 active but using Firebug both are marked active.
In IE, source code shows only 1 active but DOM explorer shows 2 active.
The CSS (active) is from Bootstrap, will have to dig deeper into the Bootstrap CSS or JS.
This happens on only 1 page, and all pages have same skin, css, js
