Trouble with slider component

I’m trying to create a slider within the tab component as a slidable portfolio. Every time I get the images on the slider and click preview, some of the slides don’t fully leave or it shows the in between space between the slider. I’ve tried multiple different ways and it works in design but when I publish or preview it seems to mess up.

The slider is located on the Photo page and I want to do the same with video on the video page

Please Help!
