Did you notice that in the earlier movies everyone, except his father, called him Indiana/Indy. He was even known as Indiana Jones as a scientist. Notice that Chatter Lal knows him under that name - only hearing about his archeological and academic work before. His coleagues also call him that.
But in KotCS it's all different. Prof. Stanforth calls him Henry, so does everyone else, except his friend from the past. But that's not all - he also refers to himself as Henry.
Remember the scene where he tells Ox who he is? He goes like:
-Listen, Ox. I'm Ind... I'm Henry Jones Jr.
He acts like it was a mistake. Something he was once used to, but doesn't think it's appropriate anymore. Why do you think this happened?
