Revolution slide shows a black slide at end

Hi
I have setup a slider based on the classic template. When the slides have all been displayed once and it gets to the end of the second showing there is a black slide displayed.

Could you please advise.

The slider can be found on halifaxboilerrepairs.co.uk

Thanks
Tony

HI,
I think I have resolved this

I changed all slides to no transition and then on global settings changed to fade and over ride all slides.

Thanks
Tony
