Target generated model doesn't work (Vuforia)

Hello everyone,

So I've downloaded the "Vuforia Model Targets" sample from the asset store, changed the database and model target with the one that I generated from "Model Target Generator" and it just doesn't work. I've noticed that I'm missing a section at the hierarchy (picture attached).

-Vuforia Version: 7.5.26

-Model Target Generator Version: 7.5.20


Thanks everyone
