Oversized images in Featured Slider

Hello I still found an error in the template. If the two checkboxes "Check to enable Scroll bar" and "Check to enable Normal Scrolling" are activated in "FullPage Options". The images of the "Featured Slider" appear oversized on the iPad, which means that the image cannot be recognized. The backgrounds of the remaining screens also appear oversized, for example in "Service". vah.ch Many thanks for the help. regards Heinz
