Sort product is not working

Hello to all, in my site the products in all categories are listed by “alphabetical order”. Check for example:
https://ntotaslight.gr/product-category/fotistika-eksoterikou-chorou/fotistika-orofis-plafonieres-fotistika-eksoterikou-chorou/

I have set the option to “Latest” from Appearance > Customize > WooCommerce > Product Catalog but stll nothing changes in my eshop. I also try other options like “Appearance > Customize > WooCommerce > Product Catalog, and check if “Default product sorting” is set to “Default sorting (custom ordering + name)” but still the default option is alphabetical order.

I dont use any plugin for this or anything else. Any idea why this is not working?

Thanks
Giorgos
