'Transaction HTTPS Request - Server Side Tagging Consolidation Stream

I have a trouble with Server Side Tagging Consolidation Stream. I am trying to use GA4 Stream to dispatch Universal Analytics data to Google Analytics. So far I managed to send data via 2 different streams - one for GA4 and one for UA and they are working fine. I have to mention also that in both situation I am using GTM4WP plugin by Thomas Geiger. But when I am trying to use GA4 stream to send data also to Universal Analytics it doesn't work as I expected. In Universal Analytics I can see purchase event in "Behaviour > Event" or "Real-time > Events" Tabs but I don't see even once transaction in "Conversion > E-commerce - Overview". I checked outgoing request and it looks like bellow (I skip some parameters) (:

tr=89
t=event
ea=purchase
ec=ecommerce

I have and idea that it doesn't work because t parameter is equal do event, not to transaction but I checked working request (without consolidation) and it also has t=event:

tr=0
ec=Enhanced%20Ecommerce
ea=gtm4wp.orderCompletedEEC
el=%2Fcheckout%2Forder-received%2F213251%2F
pa=purchase
t=event

Wham am I doing wrong here?
