Where has the engine displacement data gone?

I go to creative hub, search for tunes and in my case I like to keep cars in the class they started plus I keep the original drive trains. I dont want all of my cars sounding the same because the majority of tunes all go for similar or the same engine swaps and suddenly it’s like every car is the same. That was my experience in horizon 4. So is there any explanation as to why it’s impossible to see this info when searching tunes?
