products not showing in category on frontend Magento 2, but they are showing record count on category navigation

our items are no longer showing for each category page on the frontend.

I have checked lots of items on the admin:

Enabled = yes

Product in website = yes

Product in category = yes
Stock status in stock = yes
Visibility = catalog, search
Reset index, Reindex and flush cache = yes

Website = https://www.theemporiumdirect.co.uk/

(item blocks such as New items, related items, upsell items are showing).

Any advise would be much appreciated!
