Hi, I knew this kind of similar issue has been posted here a few times before but mine seems pretty complicated.
Here is the situation of my home page, it begins to show up some random codes related to the translation missing issue. I am using the motion theme if that helps.
You should be able to search in the filter bar for your missing fields. In your case I would recommend searching “quantity” or “from_text” to see the exact inputs, type in a piece of text you’d like to appear there in English, and Shopify will automatically translate it.
