Dope Theme - Main Page doesn't flex grow as intended

I tried messing around with the css assets (owl-stage, owl-item, owl-stage-outer etc) but to no avail, I don’t know why it doesn’t fill up the whole width, the demo shown it does.

https://dope.ghost.io/ seems like it’s by design? Looks real ugly though for larger screens

function tagFeed() {
    'use strict';
    $('.tag-feed').owlCarousel({
        dots: false,
        nav: true,
        navText: ['', ''],
        responsive: {
            0: {
                items: 1,
            },
            768: {
                items: 2,
            }/*,
            1200: {
                items: 3,
            },
            1920: {
                items: 4,
            },
            2560: {
                items: 5,
            },*/
        },
    });
}

Found it but it doesn’t auto scale
