Ghost slide in webflow slider

Hello guys!!
I’m having some problems with the webflow slider. I need do display 3 slide on desktop and 4 on tablet and mobile. When I try to style the slide itself, it says that to preserve the slider functionality you can’t edit the slide but I need to place a div block inside it and style it instaed, doing so, when hiding the 4th slide in the desktop breakpoint, just leaves the slide with nothing inside it creating a “ghost slide”. How may I solve this? thank you guys!!
