I came up for a workaround in Google Analytics to get accurate product reporting. You can find the implementation here:
I hope this is helpful!
I'm surprised this still hasn't been resolved by Shopify as of September 2019. in the EE: product detail-event, Product title still contains variant information when being sent as has been reported by multiple users in the last couple of years. Other stuff like EE product list and EE Checkout steps seem hard to impossible to implement at the moment.
When will you address this, Shopify?
