Hi @MakyBeauty and welcome to the PBC! 🙂
I've checked your website and could see that the Shopify integration of the Pinterest Tag is working as expected. However, it seems like there are traces of manually implemented Pinterest Tag on your website, I would recommend removing any manually implemented Pinterest Tag as to not interfere with the Shopify integration.
You can learn how to do so on this Help Center article.
Regarding the Conversion Campaign, bear in mind that after on of the supported events for it (Add to Basket, Checkout, Sign up or Lead) is fired for the first time, you'll need to wait 48 hours for the Conversion Campaign to be available to you.
You can learn more from our Help Center article, and if you have any questions in the meantime, let me know.
