Autoplay is not working at 3000ms

<Carousel hideArrow showDots={Dots? true: false} dot={MyDot2} gap={10} autoplay={3000} loop>

Here I am creating a carousel with 3 pictures and expecting1pic/1000ms should function but is not moving as expected while a single image should appear at once when it is working with default props.
