Facebook Pixel Error - "Same Event ID Received for Many Event Instances"

We have been using the default Shopify integration with Facebook Pixel. it worked fine up until recently. We started getting critical warning from Facebook pixel manager that "Same Event ID Received for Many Event Instances". We believe this is causing conversion events to be duplicated across multiple ad sets, i.e. double-counting conversions!

Anyone has seen this recently? This error just came out of no where. We did not make any changes.

The error went away when the Facebook app was re-integrated again. However, I don't know if the Facebook ad manager data are correct or not anymore. All these duplications are making doubt if the conversions are real
