Hi @isacto ,
Thanks for mentioning the Theme name, it's very helpful. Please take a look at this post and see if it helps: https://community.shopify.com/c/Shopify-Design/How-to-customize-delete-certain-product-sort-options-.... I'll post back in a day or so once I've played around with Venture theme. It could be a simple code change or several changes through out the theme files. Yea, just for sort seriously.
