Cree un tema con el generador de temas de shopify, pero se duplica la informacion de un producto en otro producto, como hago para que pueda personalizar cada producto?
Hello there!
Im happy to help 
This issue you’re currently facing usually happens because the theme is using shared (global) content, so when you change it for one product, it also changes for others.
To fix this, make sure the information you want to change is saved inside each product, not in the theme settings. Edit the content from Products → select the product → Description or custom fields, instead of the theme editor.
If you need different layouts or extra text per product, you can also assign different product templates so changes only apply to that specific product.
This way, each product can be customized without duplicating information across others.
Hope this helps you out!
If you have other questions or concerns, you can post it here and I will get back to you
