If’s actually your www CNAME to Shopify that’s causing this record, that points to shops.myshopify.com.which then resolves to 23.227.38.74. I would assume Shopify know that this is their own IP. Your root domain points to 23.227.38.65 which is another of Shopify’s IPs.
This doesn’t make a lot of sense given that your record for the root domain and www point to Shopify.
