Frequently bought items not appearing

Hi Support, we are using your plugin on our site, and we are having an issue with a new product I added – the frequently bought together tab isn’t showing on the page although I’ve set it up as usual in the product settings. This is the product – https://groupscs.co.uk/product/sico-usb-110-connection-set/

For context, on another similar product the tab is just below the images and works as intended – https://groupscs.co.uk/product/simon-link-lead/

Do you have an idea of how I can resolve this?
