Thank you so much for using our theme. First we recommend you to check our demo on your mobile phone and tablets and try to find the same issue. If you got the same issues on the demo as well, you need to customize the theme based on your need. Otherwise, you can use the theme features to make like the demo. As we know, you are talking about the slider, and slider is only available on the premium products of this theme. So, we recommend you to check our premium products. By the way, the URL you provided above is really nice and your website is really awesome. Loved it. 🙂
If you have any confusion, let us know.
