I also tried to go into the edit code section as it was offered as a solution on a similar inquiry, but I was not able to find the setting that they were looking to change; I think that post was outdated and I can’t even find it anymore.
Thanks for reaching out here in the Shopify Community to share your query.
Thank you also for the info and store link you also shared here, that’s really helpful!
I took a look around your store and I can confirm that this language is still in place on the product page, but I can see the text ‘FREE Shipping!’ showing on your cart page instead.
It may be the case that the instance of this language that was edited by you is the one that shows on the cart page, not the instance that shows on the product page.
Could you check for me to see if the text on your product page is part of the product descriptions added to your products, or if it is something you can find and edit in the edit language menu?
You can try searching in the language editor for the text ‘shipping calculated’ etc there to see if there are any other places that this text shows up, other than in the cart section.
Let me know how you get on with this and if you can determine if this text is part of your product description or can be edited using the edit languages menu.
