GA4 tags double fire on store, please help!

[sm_data]

We recently connected our Shopify store with GA4 and are currently using the native integration. We've noticed that the GA4 tag fires twice on our store for most events including pageviews, add to cart, and purchase. I've attempted to implement GA4 through GTM but still experienced double tag fires. This is inflating the numbers in our reporting. We have integrated other platforms such as Facebook, GTM, Google Ads, and TikTok without any issues. They all fire once as expected. Has anyone experienced this before? How can we fix this?

I'm not sure if this matters but we're using this store theme: Prestige version 9.3.0

Thanks in advance for your help.
