WGA credit on He Ran All the Way

I can't imagine who entered the writing credit this way, but the novel credit on He Ran All the Way (1951) should not read "based upon de novel "he ran all the way" by"; apart from the title capitalization, the misspelling is ridiculous, but it's WGA-locked. If you really need proof, it's on YouTube (at 0:38): https://www.youtube.com/watch?v=28xbi_YgSCo
