Add to cart event returns multiple random products in “items”

First of all, thanks to all the amazing developers and contributors to this insane plugin!

I’ve installed it on an e-commerce site and I’m having an issue with the “add-to-cart” event. When I try to add a specific product to the cart, the datalayers return several products in the “items” and not just the one I added to my cart. Has anyone had this problem? You’ll notice that the quantity is the only parameter that differentiate the added product from the random others. And the value of quantity is a string, not a number. Thanks in advance for your help.
