Why is my website's slide show not loading correctly?

[Bandicute]

Hi team. Suddenly the slide shows on my website home page are not loading correctly (all appearing as separate photos down the page) and are causing the page to load very, very slowly. This has only just happened. I think the problem is with swiper-bundle.min.css but have no idea how to fix this or why it has happened now.

Can anyone help please?

My website is www.bandicute.com.au

Many thanks

The problem seems to have rectified itself overnight. Being relatively new to Shopify I wonder if this is a regular occurrence?
