Swiper in a modal

I want to show the swiper in a modal which shows different images in a 1 by 1 view.
I set the properties Auto Height - Centered Slides - Autoplay - Loop.

When I run it in the browser the modal shows only the first image, no autoplay, no action on the controls.
Although I didn’t activate the Grab Cursor I can Grab the images .
