Next button moves ~1.5 slides. How to make it just one slide?

[DHRegular]

Hello,

I have been integrating Swiper into my wordpress theme and right now when I press on the next button, the slider shifts so much that it cuts the next slide in the middle. The amount it moves it slightly more than 1.5 too, because some slides are skipped completely, and the last "page" of the slider is completely blank.

How can I change the distance the slider moves when pressing next?
