Elementor Section/Column Looks Wrong in Preview Mode

So this is incredibly infuriating and I’ve been working for days on this trying to fix it.

On the page in question, if you scroll down below the “Browse All Brands” slider, there is a two-column Section – one that says “On Sale” and another that says “Vintage, Used & Open Box”.

In edit mode, this section stretches across the whole width of the container and looks how I designed it. Once you go into preview mode, however, it essentially makes the container a three-column container putting a large white gap to the right of the banners.

I had this working before I added more to this page, and I have tried probably 12 different things trying to get this to fix, and for the life of me I cannot get it to space out properly. I’ve remade this banner countless times and countless different ways, but no matter what, in preview mode it always looks wrong. I’m not really sure what I’m doing wrong here and I’m about to freak out.

Any help anyone can provide is greatly appreciated.
