White space / margin appearing on right side of slider

I’ve got the Meta Slider plugin installed on the home page at https://www.beaconnected.com/compass and at every slide interval, the slider is creating a margin to the right of the entire site that’s about 40px in size. I can’t target it in my dev tools and it says it’s the HTML tag, but there is no CSS in use for that.

I’ve looked at a few of your other posts, have applied “margin: 0” to both li’s and the ul of the slider, to no avail.

Any ideas? It’s difficult to target because nothing is actually appearing out there when inspected by the dev tools.
