James Caan death

Greetings, I submitted a correction (#220723-181151-679000) for the death of death of James Caan, I corrected the death from "natural causes" to "heart attack and coronary artery disease" as stated from the article below, but the result from the imdb staff was "needs attention", I submitted the correction with the link to the article, can someone from the imdb staff elaborate why this wasn't approved but needs attention? Once the imdb staff member verifies the cause of death from the article, can they approve it?

thanks for your help
