I did not develop this site, I just manage it and it has

I did not develop this site, I just manage it and it has a slider which seems to conflict with "slide-in"

The slide in appears as it should but the following happens:
- Once the slider has run through it's slides it just disappears and the page re-adjusts to show everything but the slider
- If the "close" is hit on the slide in then the slider stays but no longer cycles and just stays on the last slide .

The name of the slider is "Enigma" and the site is https://pezgato.com

Just wondering is there are any known fixes for this.

Thanks
