first slide shows rest are blank

Installed this on my theme and import a gallery from nextgen (up to date). Added to page and stuck in front it worked fine. I then tried to center the gallery managed to get this work. I then reduced the size of each slide. However I then noticed I was only seeing first slide other 7 where just plain white.

So I reset everything but I’m still getting the same problem. In the slider preview they are all show ok.

I don’t have a link to my site as it not live only local.

Any ideas why. It’s not a plugin conflict as it worked fine when first installed and no other plugins have been added.
