Influence Theme Homepage Slider is duplicated/shifted/mirrored

Hi i am having a problem with my homepage slider, i do not think i have changed anything, yet the slider now seems to show an additional thin line of the slider along the bottom, mirroring the image. This happens on all slides, i have tried replacing the slides, but this makes no difference. I have tried turing plug-ins off etc.
