Help with Andymark LED strip

[Ferrous Knight]

Hi my team bought the 8.2 ft. RGB LED light strip complete kit with Arduino controller (am-2645) from Andy-mark and we can't get it to work properly.We are using the FastLed library to program these lights but it doesn't work properly. If we tell the strip to show the first Led as red, it will light up the first 10 Leds white and the last one being blue. if we use the cylon example code modified to fit this specific strip, it will do the cylon motion for a few moments and then it will turn on a random assortment of lights afterwards. I had a couple of mentors look at it and they cant find whats wrong. We have it set up to exactly to how the instructions say and they are hooked up to a test robot we have been using. Any help would be appreciated. Attached is the pdf i have been using for reference.
