gtm4wp.orderCompletedEEC && “purchase”

On the WooCommerce Order-Complete Page, there is two dataLayer entries.
Are both of them coming from gtm4wp?

#1: gtm4wp.orderCompletedEEC
–> It carries all the data per Google Standard (DataLayer structure, names, etc….)

#2: but there is an additional event: “purchase”
–> It does not follow the “Google Standard” (so I doubt it is coming from gtm4wp)

But where is this second set of events coming from?

To illustrate, I linked to the “product detail” Page.

Since there is a “view_item” Event (also not coming from gtm4wp I assume)?

Do you guys know where I can turn these additional events (with messed up datalayer names and structure) off?
