向下滚动时图像正在放大

Question

我正在使用旋转木马显示多个图像。图像最初显示得很好，但是当我向下滚动并返回时，每个图像都会放大，占据整个屏幕。我在代码中缺少哪些基本属性？

$(document).ready(function(){
  $("#thecarousel").owlCarousel(
    {items : 3,
    loop : true,
    margin : 1,
    dots : true,
    autoplay : true,
    autoplayTimeout : 1300,
    autoplayHoverPause : false,
    responsive : {
          0 : {
              items : 1
          },
          400 : {
              items : 2
          },
          768 : {
              items : 3
          }
      }
    }
  );
});
