Carousel wrong initial size

Hello!

I have set the amount of slides visible = 5.

As you see, my site loads the slides wrong: https://dev.sourcing-house.com/verdensmaal/#maal-carousel. It presents many more than 5 slides.

However if I resize the window slightly: https://imgur.com/bVnkwuc

Then the carousel snaps into place with 5 visible slides.

What can I do to avoid this? I use Page Builder to insert the slider into a row.

Cheers prokop
