When editing Shopify themes, the template created in the backup theme may not be displayed and cannot be set in the editing screen for pages, product information, etc. In such cases, you can select it by creating a template with the same name in the live theme.
Templates that are not in the live theme cannot be selected from the product, page, or blog admin screens, so the draft theme preview screen cannot be displayed.
You can also select a template with the same name in your live theme.
