Fix problem with shopify site

On my product pages on my shopify store something odd has happened to my 'recommended for you' sections and 'recently viewed products' sections.

For example, see screenshot of desktop. There are now loads of products appearing like this, all small. It looks very bad and was never like this before. I'm not sure how many products I had in a row before, i think it was maybe 4. I really need this fixed.

And on mobile all these items are appearing below each other one by one and you can scroll down for a very long time it is very odd. I need this to be fixed so they are in a row how they were before.

For example see a product page here, on desktop and mobile- https://www.luxseaswimwear.com/collections/what-s-new/products/cozumel-green-lurex-crochet-triangle-bikini-top

If you view it on desktop and mobile you will see the issue for these sections. It is like this for all product pages

I would really like this to be fixed urgently
