Half layer mobile/ipad in Masterslider

Making a website with more than one slider. On a desktop perfect, but on a mobile or Ipad only (the right) half of the layer is visible. It’s like the picture splits in 2 halfs and the left part of the picture comes over the text-layer. So the slider (pictures) is working perfect on all “devices”, but not the tekstlayer. W’ve tried everything but we couldn’t solv it. www.los-olivos.com
