Currently I implement Google Analytics Enhanced Ecommerce, and there's an issue with purchase tracking.
I track purchases from PHP backend, so I use Google Analytics Measurement Protocol library (link leads to corresponding readme section) for PHP. And everything works fine, except one thing: revenue from purchases is displayed in Sales Performance section, but for some reason it is not displayed with corresponding product in Product List Performance section (but number of purchases is displayed correctly).
Please have a look at the picture:
P.S. Quantity is missing too.
