  1. Are you using it in the product page or somewhere else ?

  2. Instead of this {%- render ‘customer-box’ -%} try to use {{ product.metafields.custom.add_to_cart_button_fact.value }} or {{ product.metafields.custom.add_to_cart_button_fact }} in the same liquid block and let me know but make sure you are in the product template.
