Issue with Swiper JS (Styling)

Hey guys,
i have a little issue and dont know how to fix it.
I used Swiper JS to create a Swiper with a card effect.
It works perfectly but there is a styling issue. My elements have rounded corners but they appear with a background layer without rounded corners.

Did anyone know how to fix it?

Thank you very much!
