Challenge <a href="http://www.freecodecamp.com/challenges/waypoint-override-styles-in-subsequent-css" rel="nofollow">http://www.freecodecamp.com/challenges/waypoint-override-styles-in-subsequent-css</a> has an issue. Please describe how to reproduce it, and include links to screenshots if possible.</p>
<p dir="auto">When I loaded the page for this lesson, the 'Hello World" text on the right side of the screen is displayed twice for some reason.  If I reset the page, or even start editing the code, the second copy of the text disappears.  It's more of a weird error than a bug, but I thought I'd report it since I took a screenshot of it.</p>

<p dir="auto">It is impossible to return an array of the exact 3 elements the test was expecting and the array also not have a length of 3. I'm assuming there's something wrong in the test cases. Is there not a solution run against these tests to make sure they all pass together?</p>
