Navigation arrow no longer works when more than 4 images in slider?

I like the look of having 5 posts in the slider, so I’ve changed it in functions.php and loop-slider.php so that five display. The problem now is when I hit the “more” arrow on the last post of the slider, it just opens that post instead of moving to show more posts. How do I get the arrow to work again? Is there any way of moving it into the sidebar so it’s clearly visible? Take a look here: http://terilynandsushil.com
