Testimonials not scrolling correctly

Hi,
I am having problems with the testimonial scroller. I am just using the demo data, so haven’t touched the code. The 1st 2 testimonials are showing up ok, but by the time the 3rd one comes up it appears half way on the screen and then the others all appear half way as it tries to scroll back again and it goes blank.

I have disabled plugins to see if there was a conflict, but its still happening?

Any suggestions?
