stretched images

Hello,

I use the wordpress RC theme:
https://demo.wphunters.com/rc/

Who uses the slick slider.
Locally I have no worries. On the other hand once on my host, the images are stretched. Only on IOS.

When I inspect the code, I see that the width of the images = the full width of the slider.
Locally, the image width is correct.

Do you have an idea ?
