Maybe because adult gt Goku only appeared for five minutes or so at the beginning of GT, and goku's ssj4 form technically turns him into an adult. You're also forgetting that while goku was turned back into a child in GT, he still has the mindset and thought process of an adult, not a child. Goku even states this in his fight against ledgic near the start of GT.
