Section refuses to translate properly from designer to website

I have a section on a page that links to a CMS collection and acts as a kind of ‘related products’ section.

In the Designer and Preview, it looks and acts exactly as it should. It is based on other similar sections on my website that work fine (including live). However, on the live site this particular section looks nuts. It doesn’t pick up style selectors, the grid holding the related products becomes miniscule.

It is the section at the bottom.

Read-only link: Webflow - Tauranga Home Show

Live site: Discounted shed accessories at the Tauranga Home Show 3-5 May 2024 Mercury Arena Baypark

I’ve deleted and rebuilt the section only to find the exact same thing happens.
