Checkbox repeated unnecessarily at checkout

[DancingOaksNurs]

Hello there,

When customers are checking out, they are asked to click the same agreement checkbox twice. How can I edit the code so that they are only asked to check the box once? Below is the code I believe this is located in. 

</script>
<script type="application/json" id="CartJson-{{ section.id }}">
{{ cart | json }}
</script>

{% schema %}
{
"name": "Cart pages",
"settings": [
{
"type": "checkbox",
"id": "cart_notes_enable",
"label": "Enable order notes",
"default": true
}
]
}
{% endschema %}

Thanks for any advice!
