Good morning,
I don’t know what happened but I see the products in this way, where there were arrows before there were not, there was only a selectable part, even in the quantities it was not a button but it was with the drop-down menu.
In the product grid all the options appeared as in photo n°2 but I don’t want to see them,
It looks like these changes are coming from a third-party plugin. Please try deactivating the ‘Variation Swatches for WooCommerce’ plugin and check if the issue is resolved.
If the display returns to normal after deactivating it, the plugin settings may need adjustments.
