Illustrator :: Brushes And Appearance - Adding Additional Strokes To Same Line?

I am working with CS6 windows. I am having a problem when I made a brush, and add additional strokes to the same line.
 
Here is a pic of what is happening. You can see at the beginning of the arrow, there is a blue and pink link showing around the beginning of the arrow head. I added the pink and blue lines to the same line as the brush using the appearance tab. 
 
Now if I add a dash to the the pink and blue lines, this is what happens... There is a little pink and blue line at the very tip of the arrow head.  My dash options use for both the pink and blue lines.
 
My question is how to I get rid of this little line? What I am trying to do is.. use the black arrowhead on line with a stoke of 1 point black,  and then under that have a 3 point stroke of white.  In the image what is blue would be white, and what is pink would be black, and the arrowhead is correct as it is now. I had this same setup in CS4, and did not have that little line at the beginning.
 
here is my brush settings..
