Hi haroldous,
it seems you have heavily customized the theme, you are running several plugins and also deliver content through a CDN. So there is not much we can help you with as the slider displays fine without your customizations.
That means we can only recommend that you do some troubleshooting on your site (disable plugins, debug your code, etc…) as there is no way to analyze this by just having a look at your site.
By the way, it seems you are using the commercial version of the theme. Please notice that the forums on www.remarpro.com are only for free themes and commercial themes are not supported here. If you have purchased the theme, please use the premium forums. If you don’t know how to access the premium forums, please contact us.
