Title?

I am wondering about the titles of the two parts of Olympia. On the German VHS's I watched the on-screen titles for the two parts read

Olympia - Der Film von den XI Olympischen Spielen Berlin 1936

and

Olympia - Der zweite Teil des Films von den Olympischen Spielen in Berlin

Thus no mention of the "Fest der..." titles, no "1. Teil" and so on. It seems those were promotional titles and now video titles?

I'm considering whether this means some of IMDb's data should be changed. If you have any further information to share, please get in touch.
